Morphology

realize = real (semi-transparent) = real + ize

The modern sense 'become aware' is metaphorically extended from 'make real (in the mind)', so learners who know 'real' may not immediately infer 'become aware'.

Etymology

Realize comes from the root real meaning 'real' and the verb part -ize meaning 'to make'. A helpful way to remember the 'become aware' sense is to think of 'making something real in your mind' so that it suddenly feels clear and you understand it.
