6.3 The verb put, make, has the stem θη-. The present tense REDUPLICATES the initial consonant sound of the stem and adds an –ι– for ease of pronunciation.
θη– → τιθη–
Note here that θ, when reduplicated, has been changed to τ. This is because Greek does not allow ASPIRATED CONSONANTS to begin consecutive syllables. To avoid this situation, the aspirated consonants φ, θ, and χ are reduplicated by their corresponding unaspirated, unvoiced forms: π, τ, and κ (S 441). As a result, the reduplicated present tense stem θιθη– becomes τιθη-.
- The long stem vowel shortens in the plural forms.
- τιθη– for the present tense singular forms.
- τιθε– for the present tense plural forms and the infinitive.
