Adverbs of frequency express how often the action of a verb occurs.
Adverbs of time express when the action of a verb occurs.
Greek has four cases, which means that three parts of speech – pronouns, nouns, and articles – each have up to four forms, depending on how they are used in a sentence.
Subject pronouns, literally called “nominative personal pronouns” in Greek, indicate who or what is performing the action of a verb.
Most Greek verbs are type A (τύπος Α).
Type AB verbs have the same endings as B1 verbs but only one conjugation for each grammatical person.
Greek type B1 verbs have two conjugations for three of the grammatical persons.
With the exception of ζω, all type B2 verbs end in accented -ώ.
