When an Italian sentence has both an indirect and a direct object pronoun — I tell it to him, I'll bring them to you, they gave it to us — the two clitics appear next to each other and undergo two changes at once. The order is fixed: indirect before direct. The form of the indirect clitic shifts: the final -i becomes -e (so mi becomes me, ti becomes te, ci becomes ce, and so on). And for the third person, gli and le merge with the direct clitic into a single written word: glielo, gliela, glieli, gliele, gliene. Once you understand these three rules — order, vowel shift, and merging — every combined clitic in the language follows.
This page lays out the full system: the table of all combinations, the morphological logic, placement in the sentence, and the most common errors English speakers make when assembling them.
Rule 1: Order is fixed (indirect before direct)
In a sentence with both an indirect and a direct object pronoun, the indirect comes first, the direct second. This is the opposite of the order English imposes when the indirect is bare ("Give me the book" — indirect first, direct second), and it is the same as English when "to" is explicit ("Give the book to me"). The Italian order corresponds to the indirect-first English logic.
Me lo dai?
Will you give it to me? (me = indirect, lo = direct)
Te la presento volentieri.
I'll happily introduce her to you.
Ce li hanno spediti la settimana scorsa.
They sent them to us last week.
Vorrei vedervelo subito, ma è impossibile.
I'd love to show it to you guys right away, but it's impossible.
The order never changes. There is no version of any combined clitic where the direct comes before the indirect.
Rule 2: The vowel shift (-i → -e)
When an indirect clitic ending in -i (mi, ti, ci, vi, si) precedes a direct-object clitic, the final -i changes to -e.
| Alone | Combined form |
|---|---|
| mi | me |
| ti | te |
| ci | ce |
| vi | ve |
| si (reflexive / impersonal) | se |
This shift is purely phonological. Two unstressed -i sounds in a row (mi lo) feel awkward; Italian smooths the first one to -e (me lo) for an easier flow. It is always written: do not write mi lo — write me lo. The two clitics remain separate words for these five forms (me, te, ce, ve, se) — they are not merged into a single word, just adjacent.
Me ne sono accorto soltanto ieri.
I only realised it yesterday. (me + ne, separate words)
Te lo dico una volta sola.
I'm telling you this once.
Ce ne sono ancora molti, non preoccuparti.
There are still many of them, don't worry.
Ve la racconterò al ritorno.
I'll tell you guys (the story) when I get back.
Rule 3: gli/le → glie- (one written word)
The third-person indirect clitics gli ("to him," "to them") and le ("to her") behave differently from the others. Instead of just shifting their vowel, they merge with the following direct-object clitic into a single written word — and this word starts with glie-.
| + | lo | la | li | le | ne |
|---|---|---|---|---|---|
| mi | me lo | me la | me li | me le | me ne |
| ti | te lo | te la | te li | te le | te ne |
| ci | ce lo | ce la | ce li | ce le | ce ne |
| vi | ve lo | ve la | ve li | ve le | ve ne |
| si | se lo | se la | se li | se le | se ne |
| gli / le | glielo | gliela | glieli | gliele | gliene |
Two things to notice in the bottom row: the form is written as one word (no space, no apostrophe), and the same glie- prefix covers gli ("to him"), le ("to her"), and gli ("to them") in a single neutralised form. Whether the recipient is male, female, or plural, the combined clitic is identical. Context determines which reading applies.
Glielo dico subito.
I'll tell it to him / her / them right away.
Gliela presento domani sera.
I'll introduce her to him / her / them tomorrow night.
Glieli ho già spediti.
I've already sent them (the documents) to him / her / them.
Gliele restituiremo entro venerdì.
We'll return them (the keys, fem. pl.) to him / her / them by Friday.
Gliene parlerò io stesso.
I'll speak to him / her / them about it myself.
The glie- forms are always written as one word — never gli e lo, never gli'lo, never gli lo. This is the single most common spelling error that learners make with combined clitics, and it is jarring for natives because the merged form has been standard Italian for many centuries.
Why gli/le merge but mi/ti don't
If you're paying attention, you might wonder: why do gli and le merge into a single word, while mi/ti/ci/vi/si stay as two separate words?
The historical answer is that the merging happened naturally when the third-person clitics were followed by clitics starting with l-. Gli + lo in rapid speech became gliel (with the gli- /ʎʎi/ glide flowing into the l- of the direct clitic), and the spelling caught up to write it as one word. Le (to her) similarly merged: le + lo → lielo in older Italian, then standardised to glielo with the masculine form taking over as the spelling. Ne also merges with gli: gli + ne → gliene.
For the other indirect clitics (mi, ti, ci, vi, si), the phonetic environment didn't push them toward merging. Mi lo simplified to me lo (vowel shift) but never went all the way to a single word melo — perhaps because there was no third clitic in the system to drive the merging by analogy. So we have an asymmetric system: glie- is one word, the others are two.
This is the kind of asymmetry you simply have to accept. There is no synchronic reason for it; it's history showing through.
Placement: combined clitics behave like a single unit
For placement purposes, a combined clitic is treated as one block. It goes wherever a single clitic would go: before the conjugated verb, attached to an infinitive, attached to an affirmative tu/noi/voi imperative, before a Lei imperative.
Before the conjugated verb
Te lo prometto: non lo dirò a nessuno.
I promise you: I won't tell anyone.
Glielo abbiamo già spiegato due volte.
We've already explained it to him / her / them twice.
Non me ne ha mai parlato.
He has never talked to me about it.
Attached to an infinitive
The whole combined clitic attaches to the infinitive after the -e is dropped, exactly as a single clitic would.
Vorrei dirtelo prima possibile.
I'd like to tell you as soon as possible.
Non posso permettermelo, troppo costoso.
I can't afford it, too expensive.
Possiamo dargliene un po' anche a lei?
Can we give some to her too?
Attached to an affirmative imperative
Combined clitics also attach to tu/noi/voi imperatives. With the truncated imperatives da', fa', va', sta', di', the doubling rule applies — but glie- does not double its initial g (the same exception we saw for plain gli).
Dammelo subito, per favore.
Give it to me right away, please.
Diccelo se hai bisogno di qualcosa.
Tell us if you need anything.
Daglielo quando lo vedi domani.
Give it to him when you see him tomorrow. (single g — gli does not double)
Ditecelo subito se cambiate idea.
Tell us right away if you change your mind. (voi imperative)
With modal + infinitive — the clitic can climb
Just as with single clitics, a combined clitic can sit before the modal verb or attach to the infinitive. Both are correct.
Te lo voglio dire una volta per tutte.
I want to tell you this once and for all.
Voglio dirtelo una volta per tutte.
I want to tell you this once and for all.
Glielo devo spiegare con calma.
I have to explain it to him / her calmly.
Devo spiegarglielo con calma.
I have to explain it to him / her calmly.
Reflexive + direct: se lo, se la, se ne
The reflexive third-person clitic si also undergoes the vowel shift to se when it precedes a direct-object clitic. The result is a series of forms used heavily in everyday Italian:
Se lo è messo subito.
He put it on right away. (reflexive on himself + direct it)
Se la cava sempre da sola.
She always manages on her own. (idiomatic — cavarsela)
Se ne sono andati senza salutare.
They left without saying goodbye. (idiomatic — andarsene)
Me ne vado.
I'm leaving.
The forms me ne, te ne, ce ne, ve ne, se ne are the building blocks of dozens of high-frequency Italian idioms — andarsene (to leave), fregarsene (to not care), accorgersene (to realise), intendersene (to know about), occuparsene (to take care of). Drill them as a unit.
Combined clitics and participle agreement
When a combined clitic precedes a verb in a compound tense, the past participle agrees in gender and number with the direct-object component of the combined clitic. This is the same rule as for single direct-object clitics, just applied through the merged form.
Te l'ho già detta, questa storia.
I've already told you this story. (detta agrees with la — la storia, fem. sg.)
Glieli ho prestati ieri.
I lent them to him yesterday. (prestati agrees with li — i libri, m. pl.)
Ce le ha portate sua madre.
His mother brought them to us. (portate agrees with le — le torte, f. pl.)
Me ne sono dimenticato di nuovo.
I forgot about it again. (dimenticato — when ne refers back to a masculine antecedent or a generic 'it', the participle defaults to masculine sg.)
The agreement is with the direct-object part — the indirect part has no gender to begin with. Participle agreement after combined clitics is one of the more visible markers of careful Italian: native speakers feel the agreement strongly even in casual speech, and getting it right is a clear competence signal.
Common mistakes
❌ Mi lo dici?
Incorrect — when mi precedes a direct clitic, it must shift to me.
✅ Me lo dici?
Correct — me lo (separate words, vowel shifted).
❌ Ti la presento.
Incorrect — same vowel-shift rule.
✅ Te la presento.
Correct — te la.
❌ Gli lo dico subito.
Incorrect — gli + lo merges to glielo, written as one word.
✅ Glielo dico subito.
Correct — glielo, single written word.
❌ Lo te do.
Incorrect — direct clitic before indirect; the order is always indirect first.
✅ Te lo do.
Correct — indirect te, then direct lo.
❌ Gli'el dico.
Incorrect — no apostrophe in glielo. The merged form has no internal punctuation.
✅ Glielo dico.
Correct — written as one continuous word.
❌ Te l'ho detto, questa storia.
Slightly off — when l' refers back to la storia (fem. sg.), the participle should agree.
✅ Te l'ho detta, questa storia.
Correct — detta agrees with the elided la.
❌ Daggli il libro!
Incorrect — gli (and glielo, gliela...) does not double its initial g after truncated imperatives.
✅ Dagli il libro! / Daglielo!
Correct — single g in dagli and daglielo.
Key takeaways
Order is indirect-first, direct-second, always. Me lo, te la, glielo, ce ne — never the reverse.
The five non-third-person indirect clitics shift -i to -e before a direct clitic: mi → me, ti → te, ci → ce, vi → ve, si → se. They stay as two separate words with the direct clitic.
The third-person indirect clitics gli and le merge with the direct clitic into one written word starting with glie-: glielo, gliela, glieli, gliele, gliene. The same form covers "to him," "to her," and "to them" — gender- and number-neutral on the indirect side.
Combined clitics behave as a single unit for placement: before the conjugated verb, attached to infinitives and gerunds, attached to affirmative tu/noi/voi imperatives, before formal Lei imperatives. With modal + infinitive, the whole combined clitic can climb to the modal or attach to the infinitive — both correct.
The past participle in compound tenses agrees with the direct-object part of the combined clitic: te l'ho detta, glieli ho prestati, ce le ha portate. This agreement is a clear marker of careful Italian.
Watch the orthography: glielo is one word, no apostrophe; me lo / te la / ce ne are two words; gli does not double its initial g after truncated imperatives like dagli, daglielo.
