Common mistakesUsing 'height' instead of 'heights' when referring to multiple places., Confusing with 'highs' in a non-elevation context., Using 'heights' when only one height is being described.Confused with 'peek'; they sound similar but have different meanings., Using it as a verb when it should be an adjective (e.g., 'the peak time' instead of 'peaking time').Confusing 'summit' with 'peak' or 'top', as the latter may not imply a meeting., Using 'summit' to refer to any gathering, instead of higher-level meetings., Incorrectly using 'summited' as a verb form when describing reaching the peak.
