Grammar
Part of speech
Words in Greek can be divided into different categories called parts of speech (POS). Words with the same part of speech will share similar grammatical properties.
Case
English uses word order to specify the grammatical role words have in a sentence (e.g. "The dog ate the cat." versus "The cat ate the dog.") Greek, on the other hand, has a more flexible word order and instead uses case endings at the end of nouns and adjectives.
Number
In Greek, there are different word endings depending on whether the word is singular (only one) or plural (more than one).
Gender
In Greek there are three grammatical genders: masculine, feminine, and neuter. All nouns belong to one of these three genders and will have different endings according to their gender. Grammatical gender is often arbitrary and unrelated to biological sex.
Person
Grammatical person is used to indicate the person that the verb is referring to.
Tense
The tense of a verb indicates when the action happened or whether or not the action is completed.
Voice
The voice of a verb specifies whether the subject of the verb performs and action or is receiving an action.
Mood
The voice of a verb indicates the attitude of the speaker toward what they are saying, e.g. whether it is a statement of fact or a command.
