Derived Nouns: Agents, Actions, Qualities

A great deal of Afrikaans vocabulary is built, not memorised. From a single verb or adjective you can generate the person who does the action, the action itself, and the abstract quality — three nouns from one root, using three predictable suffixes. -er turns a verb into the doer (werk "work" → werker "worker"); -ing turns it into the process (beweeg "move" → beweging "movement"); and -heid turns an adjective into its abstract quality (vry "free" → vryheid "freedom"). Once you know these patterns you can produce dozens of words you were never taught, and recognise hundreds more on sight. This page covers the three high-value derivational suffixes, plus the female forms and a couple of spelling interactions. The full suffix inventory is on suffixes.

-er: the doer and the instrument

The suffix -er attached to a verb stem produces the agent — the person or thing that performs the action. This is the exact counterpart of English -er (work → worker, teach → teacher), and the parallel is so close that you can usually guess the word.

Notice the spelling mechanics. bak → bakker doubles the consonant, because the a is short and in a closed syllable, and the doubled k keeps it that way (the same logic as vowel doubling). skryf → skrywer changes the final f to w before the vowel-initial suffix — a very common Afrikaans alternation (-f to -w- between vowels). And after a stem already ending in -er or -el, the suffix expands to -aar to avoid a clumsy -erer: luister → luisteraar, not luisterer.

-er also forms instruments — the thing that does the action, not a person: oopmaak → oopmaker ("opener"), druk → drukker ("printer"), reken → rekenaar ("calculator," and by extension "computer"). Context tells you whether a -er noun is a person or a tool.

The -aar variant also appears on a fixed set of agent nouns from other roots, often around speech or moral roles: leer → leraar ("minister, teacher" in the religious sense), lieg → leuenaar ("liar"). These are best learned as whole words rather than derived on the fly.

-ing: the action or process

The suffix -ing on a verb stem produces an action noun — the activity or its result. This is roughly the equivalent of English -ing / -tion, and it is extremely productive: you can attach it to almost any verb and be understood.

Watch the spelling on beweeg → beweging. The stem ends in -eg, and the g between vowels is "soft" — but here the doubled ee shortens to a single e in the open syllable of be-we-ging, a regular consequence of the syllable splitting once the suffix is added (see open and closed syllables). You do not write beweeging. This g behaviour is the main place -ing interacts with the stem, so check the spelling of g-final stems.

A note for English speakers: do not try to manufacture Afrikaans nouns by sticking an English-style ending onto a stem. informasie ("information") and posisie ("position") exist as borrowed -sie nouns, but you cannot coin "beweegsie" for "movement" — the real word is beweging, with -ing. When in doubt, -ing is the safe native choice for an action noun.

-heid: the workhorse abstract suffix

If you learn one derivational suffix on this page, learn -heid. It attaches to an adjective and produces the abstract quality noun — the English equivalents are -ness, -ity, -dom, -th. It is completely regular and stacks predictably on almost any adjective, so it generates dozens of words at once.

The suffix never changes shape and never takes a diacritic — it is always -heid. The plural is the only complication: -heid nouns pluralise to -hede, not -heids: waarheid → waarhede ("truths"), geleentheid → geleenthede ("opportunities"). This irregular plural is worth memorising because it is so frequent.

A close relative is -teit, the borrowed equivalent for Latinate adjectives (universeel → universaliteit, aktief → aktiwiteit "activity"). Use -teit only with obviously borrowed, scholarly roots; for everyday adjectives, -heid is the native, productive choice. The broader picture of abstract versus concrete nouns is on abstract and concrete nouns.

Plurals of derived nouns

The good news: most derived nouns pluralise completely regularly, so you can use them at once.

So -er and -ing nouns take a plain -s; only -heid breaks the pattern with -hede. The general plural system is on plurals overview.

Female forms: -es and -in

Afrikaans, like English, has largely dropped grammatical gender, so most agent nouns are neutral ('n leser is a reader of either sex). A few inherited pairs survive with a female suffix, mostly in fixed vocabulary rather than as a living rule:

• -es: eienaar → eienares ("owner, f."), sanger → sangeres ("singer, f."), onderwyser → onderwyseres ("teacher, f.").
• -in: held → heldin ("heroine"), boer → boerin ("farmer's wife / farming woman"), vriend → vriendin ("female friend / girlfriend").

These are not productive — you cannot freely coin new ones — so treat them as fixed words. The default in modern Afrikaans is to use the base form for any gender unless the -es/-in form is the established word. The complete suffix list, including these, is on suffixes.

Common mistakes

Key takeaways

• -er builds the doer or instrument from a verb (werker, leser, rekenaar), mirroring English -er; stems ending in -er/-el take -aar (luisteraar) to avoid -erer.
• -ing builds the action or process (beweging, betaling, oplossing) and is highly productive — the safe native choice for an action noun, never an invented -sie.
• -heid is the workhorse abstract suffix: adjective → quality noun (vryheid, waarheid, gesondheid), regular and stackable; its plural is the irregular -hede.
• Most derived nouns pluralise with plain -s (werkers, bewegings); only -heid uses -hede. See plurals overview.
• Female -es / -in forms (sangeres, vriendin) are fixed vocabulary, not a productive rule; the base form is the modern default.
• Watch the spelling interactions: bak → bakker (consonant doubling), skryf → skrywer (f → w), beweeg → beweging (ee shortens). For the full inventory, see suffixes.
