Etymology
the word 'semitropical' is a modern english compound formed by combining the latin prefix 'semi-' with the adjective 'tropical'. the latin 'semi-' directly denotes 'half' or 'partially', a concept traceable to proto-indo-european sēmi-. the base 'tropical' originates from greek 'tropikos', derived from 'tropē' meaning 'a turning', specifically referring to the turning points of the sun at the solstices which demarcate the torrid zone. therefore, the literal construction 'half-tropical' logically evolved to describe geographical zones that share some, but not all, characteristics of the true tropics, such as having a climate that is warm and humid but subject to occasional frosts or cooler seasons.
Analysis
Structure: semi (half) + tropical (of the tropics)
semi: from latin 'semi-', meaning 'half'. a prefix indicating partial or incomplete nature.
tropical: from greek 'tropikos', via latin 'tropicus', meaning 'of or pertaining to the turning (of the sun at the solstice)'. it functions as the base adjective.
