A combination of -tō and -itō.
-titō (present infinitive -titāre, perfect active -titāvī, supine -titātum); first conjugation
Many verbs ending in -titō are simply "double frequentatives", formed to already-frequentative verbs in -tō, and are therefore not truly uses of this suffix. However, some verbs exist where the "intermediate" single frequentative is missing, e.g.:
tito (複数形 titos)
