Morphology

keep + a + close + watch

The meaning is directly built from 'keep' (maintain/continue) + 'close' (near/intense) + 'watch' (observe), so a learner who knows these words can infer 'monitor carefully'; the article 'a' is syntactic only. This verb + adjective + noun composition is cross-linguistically common and follows a transparent, compositional pattern.

Etymology

Keep a close watch comes from the image of a guard who keeps a close watch, standing very near and looking for any small change. That's why it means 'to watch someone or something very carefully'.
