We begin building the verb form with the Lexical Morpheme. Over the next few steps morphologically we will progressively add morphemes with grammatical and syntactic information, and phonetically we will see how the sounds of those morphemes interact with other sounds in the word to produce the verbal forms that we see.
First, morphologically, we set up Aspect. The punctiliar aspect morph -σα- is added to this (inherently) durative lexical morpheme σκευαζ- to change the aspect of this verb form to punctiliar.
Second, phonologiclly, the lexical morpheme σκευαζ- ends with a ζ (zeta) that was originally (historically) a sillibant. The σ (sigma) of the puntiliar aspect morph assimilates the silibant ζ before it and then combines with it so only one σ (sigma) is written. (In effect, the ζ (zeta) is lost from the word).
Third, morphologically, the third person singular secondary ending -ε(ν) is added to the end of the verb. The ν is parenethesised because it is only sometimes spoken/written for this verb ending - before a consonant it is silent and before a vowel the ν ("nu") is still spoken/written.
Fourth, phonetically, the punctiliar aspect morph -σα- is an elision morph - the final vowel α ("alpha") elides (ie it is lost) rather than combining with the following vowel.
Fifth, morphologically, the the past time marker is added to the front of the verb to explicate that the verb is past tense. In this case, it stands alone as an extra syllable prefixed to the verb - called the "syllabic augment".
Sixth, phonetically, the preposition παρά is one of the (proper) prepositions that loses its final alpha before a vowel - in this case the augment of the verb.
Seventh, morphologically, in some circumstances, the preposition that adds meaning to a simplex verb form is prefixed directly onto the verb form.
Eighth, the accent of this verbal form is recessive. The final vowel of the verb form epsilon ("ε") is theoretically short, so the accent will be on the antepenultimate syllable (ie the third last syllable). Counting back three syllables - ultimate, penultimate, antepenultimate - it is the upsilon ("υ") of the lexical root σκευ-. The only possible accent on the antepenultimate syllable is the acute.
