Spelling D/T and V/F, Z/S | Dutch Grammar

Dutch makes you write letters you cannot hear. You say "hont" but write hond; you say "rijt" but write rijdt; you say "brief" but the f was an v a moment ago in brieven. This drives English speakers up the wall, because English mostly lets you spell what you say. The key that unlocks all of it is one principle: Dutch spells the consonant that appears when you extend the stem with a vowel. Once a vowel follows the consonant, its true voiced/voiceless identity is revealed — and that revealed letter is the one you write everywhere, even where the sound devoices and the truth goes silent. This page handles d/t and v/f, z/s; the open/closed doubling rule is in open and closed syllables, and the verb-ending 't kofschip rule for the past tense is in weak verbs: -te vs -de.

💡

The whole page reduces to one move: extend the word with a vowel and listen. The consonant you hear in the extended form (honden, worden, brieven) is the consonant you write in the base form (hond, wordt, brief) — even when pronunciation devoices it.

The principle: recover the letter from the extended form

In Dutch, a consonant at the end of a word (or before another consonant) devoices — d sounds like t, v like f, z like s (the pronunciation side is in final devoicing). But spelling doesn't follow the sound; it follows the morphology. To find the right letter, add an ending that starts with a vowel — usually the plural or the wij-form — and the consonant un-devoices, showing its true colours:

hond sounds like "hont", but the plural is honden → the real letter is d, so you write hond.
hij wordt — the stem is word (from worden) → the real letter is d, so you write word
- the t ending.
brief sounds like "brief", but the plural is brieven → the real letter is v, surfacing as f only when it ends a syllable.

This is why two words that sound identical can be spelled differently: hard ("hard") and hart ("heart") both sound like "hart", but harder reveals the d in hard, while harten reveals the t in hart.

D/T at the end of a noun or adjective: hond, hard

For nouns and adjectives, the rule is simply: write the consonant the plural (or another vowel-extension) shows you.

hond — honden

'dog' — 'dogs': the plural honden has an audible d, so the singular is hond, even though it sounds like 'hont'.

hard — harder

'hard' — 'harder': the comparative reveals the d; sounds like 'hart' but is written hard.

land — landen

'country' — 'countries': landen confirms the d; the singular land sounds like 'lant'.

The same logic catches the t words, so you don't over-correct: if the extension shows a t, you write t.

hart — harten

'heart' — 'hearts': harten reveals a t, so it's hart, not hard — even though it sounds identical to hard.

D/T on verbs: the silent t in hij wordt and hij rijdt

This is the one that defeats everyone, because the crucial t is completely inaudible. The present-tense rule for hij/zij/het is stem + t. When the stem already ends in -d, you still add the t — giving a written -dt that sounds like a single "t".

The stem of worden is word (drop -en: word-). So hij + stem + t = wordt. You hear "wort", but you write word + t = wordt. Same for rijden, stem rijd: rijdt.

Infinitive	Stem	hij/zij/het form	Sounds like
worden	word	hij wordt	"wort"
rijden	rijd	hij rijdt	"rijt"
vinden	vind	hij vindt	"vint"
houden	houd	hij houdt	"hout"

Hij wordt volgend jaar dertig.

'He turns thirty next year.' — stem word + t = wordt, even though you only hear one 't'.

Zij rijdt elke dag naar haar werk.

'She drives to work every day.' — stem rijd + t = rijdt.

Crucially, the ik-form is just the bare stem, with no t: ik word, ik rijd, ik vind. So the trio ik vind / hij vindt / vinden all share the stem vind-; only the endings differ. (For why a learner constantly trips over word/wordt/worden, see the dt-errors page.)

Ik vind dat hij gelijk heeft.

'I think he's right.' — ik + bare stem: ik vind, NO t.

Wat vind jij ervan? — Wat vindt hij ervan?

'What do you think?' vs 'What does he think?' — jij after the verb takes no t (vind jij), but hij always takes the t (vindt hij).

V/F and Z/S: the syllable-edge swap

Dutch has a strict rule: v and z never end a syllable. When a v or z would land at the end of a syllable (typically the end of a word), it is rewritten as its voiceless partner — v → f, z → s. Add a vowel-ending and the original v/z comes back, because now it begins a new syllable.

brief — brieven

'letter' — 'letters': the plural brieven has a v; at the word's edge it's written f → brief.

huis — huizen

'house' — 'houses': huizen has a z; the singular ends a syllable, so z → s → huis.

lief — liever — liefde

'sweet/dear' — 'sweeter': the comparative liever shows the v; lief and liefde write f because the v would end a syllable.

The same swap happens inside a word the moment a consonant follows, closing the syllable off:

half — halve

'half': the inflected halve has a v (vowel follows); half writes f because the v would close the syllable. Same word, two spellings.

wolf — wolven

'wolf' — 'wolves': wolven reveals the v; the singular wolf writes f at the syllable edge.

💡

Verbs that begin with these sounds always start a syllable, so they keep the v/z in the infinitive — leven, geloven, verhuizen. But the moment you make a stem that ends the word, it flips: ik leef (stem of leven), ik geloof, ik verhuis. Same recovery rule, applied to verbs.

leven → ik leef

'to live' → 'I live': the infinitive keeps v (it starts a syllable); the stem ends the word, so v → f.

Common Mistakes

These are the four errors English speakers make most — all from spelling the sound instead of the recovered letter.

❌ hij word (no t)

Wrong — the hij-form is stem + t; the stem word already ends in d, so it's word + t = wordt.

✅ hij wordt

'he becomes/turns' — the silent extra t is required.

❌ honden spelled fine, but the singular written 'hont'

Wrong — the plural honden reveals the d; the singular is hond, despite sounding like 'hont'.

✅ hond

'dog' — recover the d from honden.

❌ brief written 'briev', huis written 'huiz'

Wrong — v and z never end a syllable; at the word's edge they become f and s.

✅ brief — huis

'letter' — 'house': the v/z return in brieven/huizen.

❌ ik wordt / ik rijdt (with a t)

Wrong — the ik-form is the bare stem with NO t: ik word, ik rijd.

✅ ik word — ik rijd

'I become' — 'I drive': no t on the ik-form.

❌ mixing up rijd / rijdt / rijden

Wrong — ik rijd (bare stem), hij rijdt (stem + t), wij rijden (infinitive/plural). All share the stem rijd-.

✅ ik rijd, hij rijdt, wij rijden

'I drive, he drives, we drive' — one stem, three endings.

Key Takeaways

Dutch spells the underlying consonant, recovered by extending the stem with a vowel — honden shows the d in hond, brieven the v in brief.
A word-final d is written d even though it sounds like t (hond, hard, land); check the plural to confirm.
The hij/zij/het verb form is stem + t, so a d-final stem gives a written but inaudible -dt: hij wordt, zij rijdt, hij vindt. The ik-form is the bare stem with no t.
v and z never end a syllable: they flip to f and s at a syllable edge (brief/brieven, huis/huizen, half/halve, ik leef from leven).
When in doubt, extend with a vowel and listen — the form that follows reveals the letter you must write.
