Koine Greek/Future Indicative

The future and future perfect tenses indicate future actions. The future tense, which simply adds a sigma between the verb stem and the regular present tense ending, has both perfective and imperfective aspects. However, the future perfect has a perfect aspect. In other words, the future tense generally conveys both continuous and discrete actions (e.g., δουλεύσω: I will work, I will be working), though some verbs like ἔχω have aoristic and imperfective future tenses (e.g., ἕξω: I will be having; σχήσω: I will have).

When paired with certain consonants in verb stems, the sigma and consonant merge to form a new consonant or fall away(as is the case with the Dentals) leaving only the sigma. Verbs with vowels at the end of their stems(λυω for example ) need not undergo this change as we can simply insert the sigma between the stem and ending (λυω -> λυσω).
