An insert in the middle
Most verbs in -ire slip an extra syllable between the stem and the ending in the present: -isc-. From cap- and -o you get not capo but capisco. Not every -ire verb does this (dormo, parto), and the infinitive does not tell you which. So learn each new -ire verb together with its io form.
