Morphology
change + horses + in + midstream
The phrase creates a clear literal image — swapping horses in the middle of a stream is risky and ill-advised — so a learner who knows 'change', 'horses', 'in' and 'midstream' can infer it warns against changing plans, strategies, or leaders during an ongoing process. However, it is a proverb-like metaphorical extension rather than a strictly compositional phrase, so the precise pragmatic target (e.g. leaders versus other kinds of changes) may not be fully predictable without prior exposure.
Etymology
Change horses in midstream may come from the image of someone crossing a river on horseback. Trying to change horses in the middle of the water (midstream) would be dangerous and slow, so the saying now means 'to change plans, strategies, or leaders while something is already happening' and warns that this is often 'risky' or unwise.
