IPA: /ˌɛpɪˈkjuːtɪkələr/
KK: /ˌɛpɪˈkjuːtɪkələr/
Referring to the outermost layer of a plant's cuticle, which is a protective film covering the epidermis of leaves and stems.
The epicuticular wax on the leaves helps to reduce water loss.
Epicuticular is formed from "epi-" (meaning upon or over) and "cuticula" (from Latin, meaning skin or outer layer). The word refers to something that is situated on the outer layer of a surface, particularly in biological contexts.
Think of something that is 'upon' ('epi-') the 'skin' ('cuticula') — this helps you remember that 'epicuticular' refers to a layer on the outer surface.
