“ If fulfillment is likely (and such contingencies are related to future time) , then the if-clause will have ἐάν with the subjunctive and a future indicative (or an equivalent) will stand in the conclusion. This form is styled "future vivid." E. g., ἐὰν τοῦτο πράττῃ, καλῶς ἕξοι. If fulfillment is less than likely ("future less vivid") , εἰ with the optative will stand in the if-clause, the optative with ἄν (potential optative) in the conclusion. ”

“ In learning a new alphabet attention need be paid only to such letters as are not already know. Of the Greek alphabet only twelve characters are unfamiliar:
Note.—The small letters, most used, should be learned. The capital letters may be learned as they occur.
2. ε, ο are always short; η, ω, always long; α, ι, υ, sometimes long, sometimes short.
Note 1.—In diphthongs with a long vowel ι is subscribed. ”

“ A scholarly knowledge of Greek requires some time and effort. Every preacher and teacher of the New Testament books would be greatly helped by being able even to refer to the dictionary and to pick out the critical notes in a high-grade commentary. ”

“ In case the verb itself begins with a vowel, the initial vowel is lengthened. E.g., ἀ-κού-ω, ἤ-κου-ο-ν. Bt. 171-2; Gl. 264, 293; Gn. 465, 3; H.A. 354-7.
7. The theme vowel immediately follows the stem. In the indicative it is —ο— before μ and ν, otherwise —ε—; in the subjunctive, —ω—or —η—; in the optative (mode vowel) , —οι— or —αι— (aorist passive indicative, —ει—) . E. g., ἔ-λυ-ο-ν, ἕ-λυ-ε-ς, λύ-ω-μαι, λύ-η-ται, λυ-οί-μην, λυ-σαί-μην. Bt. 159-60; Gl. 294-5; Gn. 568, 719, 730; H.A. 372.
(1) In aorist tenses except second aorist and aorist passive, the theme vowel is —α—. ”

“ A conditional sentence is one that assumes what may or may not be true (in reality) , and bases on it some other statement (i. e., the supposition is assumed to be true) . Bt. 600-1; Gl. 645; Gn. 1381; H.A. 889.
2. A simple supposition implying nothing as to fulfillment, has the indicative (or an equivalent; Bt. 602, notes) in both clauses.
(1) If a specific sequence is made in present time, then the present indicative stands in both clauses. If in past time, a past indicative occurs in both clauses. ”

“ The future tenses (future, future perfect) are indicated by a σ (+ ο/ε) appended to the stem, as λύ-ω, λύ-σω, λε-λύ-σ-ο-μαι, λύ-θή-σ-ο-μαι. Bt. 212; Gn. 662; Gl. 277; H.A. 372.
5. The perfect tenses (perfect, future perfect, pluperfect) are indicated by (1) the doubling of the stem (i. e., repeating the initial consonant with ε—) , and (2) in the active voice by an affixed —κ— (cf. Latin —v—) . E. g., λύ-ω perf. λέ-λυ-κα (for λύ-λυ-κα) .
Note 1.—If the verb begins with a middle or rough mute, the reduplication occurs with the corresponding smooth mute (cf. I,3) . ”

“ Middle participles are of the first and second declensions and may be recognized by the syllable —μεν—. E. g., λυ-ό-μεν-ος.
15. The active infinitive regularly ends in —ειν —εν + theme vowel —ε—, contracted, —ειν) . E. g., λύ-ειν (for λυ-ε-εν) . The passive and middle (i.e., when used as passive) infinitives regularly end in —σθαι. E. g., λύ-ε-σθαι, λύ-σ-α-σθαι. The aorist passive infinitive ends in —ναι. E. g., λυ-θῆ-ναι. Bt. 167; Gl. 162, 273, 275; Gn. 301, 334.
16. Variations from the regular forms occur in the endings of the imperative:
17. ”

“ The stem is the basic part of the inflected word. To this are appending the various signs, as above, which in verb analysis must again be cut off. E. g., τι-μά-ω, I honor, stem τῑμᾰ. Bt. 157-61; Gl. 248; Gn. 404-7, 153; H.A. 153.
3. The tenses of the verb are called primary or secondary as they have to do with present (or future) or past time. Taking the verb λύω as a model we have:
