Doer Nouns (-ja)
Drop -ma and add -ja: õpetama gives õpetaja (teacher), lugema gives lugeja (reader), müüma gives müüja (seller), and avama gives avaja (opener).
How It Works
The suffix -ja is one of the most useful ways to make new words. Take the ma-infinitive, drop -ma, and add -ja:
- õpetama → õpetaja (teacher)
- lugema → lugeja (reader)
- müüma → müüja (seller, shop assistant)
- laulma → laulja (singer)
- ostma → ostja (buyer)
- kasutama → kasutaja (user)
Person or device. Most -ja words name a person, often by their job. Some name a tool or machine, especially inside compounds: pudeliavaja (bottle opener), tolmuimeja (vacuum cleaner, literally dust sucker), kaardilugeja (card reader).
e becomes i in a few verbs. Some short verbs with a stem in e whose simple past is made with -i change that e to i: tegema (tegin) → tegija, tulema (tulin) → tulija, nägema (nägin) → nägija, pesema (pesin) → pesija. Lugema forms its past with -si- (lugesin), so it keeps its e: lugeja.
No gender. Estonian has no grammatical gender, so õpetaja means a teacher of any gender. The noun declines regularly: õpetaja, õpetaja, õpetajat; plural õpetajad, õpetajate, õpetajaid. It also combines freely with other nouns: muusikaõpetaja (music teacher).

lugejaid is the plural partitive.

Common Mistakes
Keeping the e in verbs like tegema and tulema.
Ta on tõeline tegeja.Ta on tõeline tegija.Short e-stem verbs with a past in -i (tegin, tulin) change e to i before -ja: tegija, tulija.
Adding an extra vowel after a consonant stem.
Ta on väga hea laulija.Ta on väga hea laulja.The stem of laulma is laul-, so -ja joins it directly: laulja. In the same way, ostma gives ostja.
