Declining the Personal Pronouns

A personal pronoun in English changes shape only a little — I becomes me, he becomes him, and that's nearly the end of it. A Croatian personal pronoun changes for all seven cases, and in the oblique cases it does something English has no parallel for: it splits into two forms per cell, a short unstressed clitic (me, ga, mu, joj) and a long stressed full form (mene, njega, njemu, njoj). This page lays out the complete grid for ja, ti, on/ono, ona, mi, vi, oni. The single insight that makes it usable: you are not memorising seven random tables, you are learning the clitic/full system applied to every person at once — clitic by default, full form after a preposition and for emphasis. Get that, and the grid becomes a tool rather than a wall.

The full grid

Each cell that has two forms shows full / clitic in that order. A dash means the clitic is identical to the full form (true for nas, vas in the accusative) or that no clitic exists (nominative, instrumental, locative — clitics never appear in those slots).

A few features jump out and are worth saying aloud. The genitive and accusative full forms are identical for the singular persons (mene, tebe, njega), as they are for nouns of the masculine animate type — so you really learn one form for two cases. The dative and locative are always identical (meni, tebi, njemu, njoj, nama, vama, njima); the locative simply has no separate shape and never appears without a preposition. And the clitics live only in the genitive, dative, and accusative rows — there is no clitic for the nominative, instrumental, or locative, because those slots are always either subjects or governed by prepositions, and a clitic can be neither.

The clitic is the default; the full form is the special tool

In any plain sentence, the oblique pronoun is the clitic. "I know him" is Poznajem ga, not Poznajem njega. "He told me" is Rekao mi je, with the light mi. You reach for the full form only when one of three things forces you to: a preposition stands in front of it, you want to emphasise or contrast it, or it has to stand alone with nothing to lean on. This is exactly the system treated in detail on clitic vs full forms — the grid above is simply that system spread across every person.

After a preposition: always the full form

This is the hard rule that gives the full forms most of their work. A clitic is unstressed and cannot bear the weight a preposition throws onto its object, so every preposition takes the full form: za mene (for me), o njemu (about him), k njoj (toward her), s njim (with him), bez njih (without them), na nas (onto us). The clitic versions — za me, o mu, s ih — simply do not exist in standard Croatian. The moment you see a preposition, the pronoun behind it flips to full automatically.

The cases that prepositions govern are mapped on prepositions and case; for pronouns the practical upshot is just that a preposition forces the full column.

The instrumental 1sg: sa mnom

One cell deserves a warning because it surprises everyone: the instrumental of ja is mnom (or the longer mnome), and because the instrumental of accompaniment almost always rides on the preposition s/sa, you usually meet it as sa mnom — "with me". The form s/sa takes the sa spelling here precisely to ease the consonant pile-up before mn-, so "with me" is sa mnom, not s mnom. The parallel forms are s tobom (with you), s njim (with him), s njom (with her), s nama (with us), s vama (with you), s njima (with them).

The third-person stem nj-

Notice that every third-person full form starts with nj-: njega, njemu, njega, njim, nje, njoj, nju, njom, njih, njima. That nj- is historically a leftover of a fused preposition, and it is the reason the third-person clitics (ga, mu, ga, je/joj/ju, ih, im) look so unlike their full partners — the clitics dropped the nj- entirely. So ga and njega are the same word in two weights, even though they share no letters. The feminine accusative has the extra wrinkle that the clitic is ju or je depending on the surrounding clitics, handled on its own page, the je/ju choice.

Plural persons: fewer surprises

The plural pronouns are gentler. For mi and vi the accusative and genitive full forms (nas, vas) are spelled the same as their clitics — they differ only in stress and position, so you can treat them as one shape on paper. Their datives split into the longer full nama, vama and the short clitics nam, vam. The third-person plural oni (and feminine one, neuter ona) collapses to a single set of forms regardless of gender in every oblique case: njih/ih, njima/im. So however many genders are in the room, "them" is njih or ih.

Clitics obey second position

Using the grid correctly is half forms and half placement. The clitics lock into the second position of the clause, right behind the first stressed word or phrase. With a bare verb the verb comes first and the clitic follows (Vidim ga), but the moment another word opens the clause the clitic jumps behind it (Danas ga vidim). The full forms, being stressed words in their own right, go wherever emphasis sends them. The mechanics are on the second-position rule.

Common Mistakes

Key Takeaways

• Personal pronouns decline for all seven cases, and in the oblique cases they split into a clitic (short, unstressed) and a full form (long, stressed).
• The genitive and accusative full forms coincide for singular persons (mene, tebe, njega); the dative and locative always coincide (meni, tebi, njemu).
• Clitics exist only in the genitive, dative, and accusative — never in the nominative, instrumental, or locative.
• Use the clitic by default; switch to the full form after a preposition, for emphasis, or when the pronoun stands alone.
• The 1sg instrumental is the irregular sa mnom; all third-person full forms begin with nj- (njega, njoj, njima).
• Clitics obey the second-position rule; full forms go where emphasis wants them.
