Morphology
trimester = semester (transparent) = tri + mester
Formed from the prefix 'tri-' (three) applied to the '-mester' element (as in 'semester'/'-mester' meaning a month/term); the 'three-month/three-term' sense for academic division is directly inferable.
Etymology
Trimester comes from the Latin parts tri- 'three' and mensis 'month'. So it literally means 'three months', which is why some schools divide the year into three trimesters.
