👀 見 (look) + 直 (again/straighten) + す (verb) = look over again, to review
見 means to look or see, and 直 here means again or anew. Together they form the verb 'to look over again,' which is exactly how you review notes or work.
直 — 十 ten + 目 eye + 乚 hidden line
Originally depicted an eye (目) looking straight along a vertical line, suggesting a direct, unswerving gaze. The form combines 目 'eye' with strokes indicating straightness. From this came the meanings 'straight,' 'upright,' and by extension 'honest' or 'direct.'
