Morphology

catch + off + guard

The meaning 'to surprise someone so they are unprepared' is directly derivable from combining 'catch' (to seize or take by surprise) with the phrase 'off guard' (not on guard, unprepared). This compositional relationship follows a clear and common English pattern (and has parallels in many languages), so a B1 learner who knows the constituent words would likely infer the meaning.

Etymology

The phrasal verb catch off guard comes from the image of a guard who is 'off' and not watching. To catch someone when their guard is off is to surprise them, so the phrase means 'to surprise someone who is unprepared'.
