-lo

-lo (front vowel harmony variant -lö)

-lo

1. enclitic form of lo; appended to present active infinitive verb forms to derive accusative forms when the object is third singular masculine person

   dare (“to give”) → darlo (“to give him”)

   vendere (“to sell”) → venderlo (“to sell him”)

   servire (“to serve”) → servirlo (“to serve him”)

2. enclitic form of lo; appended to second singular person imperative forms

   sii (“be!”) → siilo (“be him!”)

   mangia (“eat!”) → mangialo (“eat him!”)

The final -e of the original infinitive is removed :

-are → -arlo

-ere → -erlo

-ire → -irlo

Where the verb ends in -rre, the final re is removed, leaving behind just an -r:

introdurre (“to introduce”) → introdurlo (“to introduce him”)

In any case, after the suffixation, there is only a single r and no vowels immediately before -lo.

-lō

1. dative masculine singular of -lus
2. dative neuter singular of -lus
3. ablative masculine singular of -lus
4. ablative neuter singular of -lus
