17.16 The FUTURE TENSE of most όω verbs is formed regularly, with one slight change. When the tense marker σ is added to a verb stem ending in o, the o lengthens to ω. As a result, most όω verbs form their future active by adding –σω to the lengthened vowel, resulting in the ending –ώσω. The future tense then conjugates regularly, using –ω personal and infinitive endings.
Note the PRINCIPAL PARTS of the following όω verbs.
- ἀξιόω ἀξιώσω, consider worthy, valuable
- δηλόω δηλώσω, show
- φανερόω φανερώσω, reveal
