17.6 The FUTURE TENSE of most έω verbs is formed regularly, with one slight change. When the tense marker σ is added to a verb stem ending in ε, the ε lengthens to η. Most (not all!) έω verbs form their future active by adding –σω to the lengthened vowel, resulting in the ending –ήσω. The future tense then conjugates regularly, using thematic personal and infinitive endings.
Note the PRINCIPAL PARTS of the following έω verbs.
- ἀδικέω ἀδικήσω, commit injustice
- αἱρέω αἱρήσω, grab
- ἀναιρέω ἀναιρήσω, raise up

- αἰτέω αἰτήσω, beg, ask
- βοηθέω βοηθήσω, help
- δέω, δεήσω, lack, miss, be in need of (+ gen.)
- Note that the –ε of δέω remains when forming its future tense!
