Morphology

subinterval = interval (transparent) = sub + interval

The prefix 'sub-' meaning 'smaller/under' combined with the noun 'interval' directly yields 'subinterval' (a smaller part of an interval), which is straightforward for learners.

Etymology

The word subinterval comes from the prefix sub- meaning 'under' or 'below' and the word interval meaning 'a space or time between'. So a subinterval is simply a smaller interval inside a larger one, like a short section of time or a small piece of a number line.
