Morphology

2nd + thought

The meaning 'an act of reconsidering' follows directly from combining 'second' (a subsequent one) with 'thought' (an idea), so a learner who knows both words can infer it refers to another or subsequent idea about the same matter. This ordinal + mental-state composition is common and matches the frequent pattern 'on second thought', making it immediately comprehensible to a B1 learner.

Etymology

Second thought comes from the simple idea of having a second thought after the first one, a new idea that makes you pause. So it means 'to reconsider' or 'to change your mind'.
