Morphology

sub-interval = interval (transparent) = sub + interval

The prefix 'sub-' meaning 'under/part-of' combined with 'interval' yields the straightforward meaning 'an interval contained within another'; learners who know 'sub-' and 'interval' can derive it.

Etymology

Sub-interval breaks into sub- meaning 'under' or 'below' and interval meaning 'the space between' two points, so you can picture it as a smaller piece inside a larger gap. That's why a sub-interval is an interval that sits entirely 'inside' another interval.
