Sense: verb/3
All four words describe examining a location, but they differ in purpose and register. 'Case' is informal slang used almost exclusively for planning a crime — it carries a strong implication that the observer intends to steal from the place. 'Reconnoitre' is formal, from military language; it means surveying an area for strategic purposes (enemy positions, terrain) and is very rare in everyday speech. 'Scout out' is neutral and general — you can scout out a restaurant before a date or a hiking trail before a trip. 'Check out' is the most casual and broad of the group; it can mean to look at anything with any degree of curiosity ('Check out that new café'). When you want to suggest a criminal purpose, choose 'case' to be specific; for all other purposes, 'scout out' or 'check out' are more appropriate.

Etymology
Comes from the noun 'case' (a container or covering), which entered English from Old French 'cas' (box), tracing further back to Latin 'capsa' (a box or repository). The verb senses developed gradually: the general meaning 'to put in a case' was used from the 1500s. The technical sense for lining a well shaft appeared in the late 1800s with the growth of oil drilling. The slang sense 'to inspect a place for robbery' emerged in American English around the early 1900s, probably from the idea of 'putting a case around' a place by studying its boundaries and weak points.
