Inside the app

17 grammar topics
We keep working on the grammar trainer: adding exercises and topics, expanding the examples and improving explanations of mistakes.
Choose one topic or combine selected topics and exercise types in a mixed review. For the present tense, you can focus on a conjugation type: Α, Β1, Β2, contracted verbs, Γ1 (-ομαι) or the verb είμαι. The topics below use the descriptions from the app:
- Nominative Focus on the subject, predicate nouns with είμαι, and nominative articles.
- Accusative Target direct-object forms and accusative usage.
- Genitive Focus on possession, relation, and genitive forms.
- Accusative vs genitive Resolve confusion between competing case forms.
- Articles Practice article changes without extra noise.
- Pronouns Work through possessive and object pronoun forms.
- Agreement endings Choose adjective and participle-like endings that match gender, number, and case.
- Present tense Translate from and into Greek: the verb ending alone marks person and number, with no pronouns.
- Past tense (A1-A2) 20 core verbs: aorist patterns and personal endings.
- Past tense (B1-B2) 21 B1-B2 verbs: the -ησα / -ασα / -εσα patterns and personal endings.
- Future tense Train future forms, present-to-future patterns, and common exceptions.
- Perfect (έχω + -ει) A result that holds now: έχω γράψει against έγραψα.
- Imperative mood Practice commands, prohibitions, forms for εσύ and εσείς, and clitic order.
- Να + verb (subjunctive) Practice να-constructions: verb forms and clitic pronouns.
- Mediopassive (-ομαι / -άμαι) Verbs like κοιμάμαι, ντύνομαι, έρχομαι and their endings.
- Conditionals (αν … θα …) A real condition in the future: αν + future form without θα, θα + future.
- Word order Tap tokens into the correct sentence order.
