Hesitater → The word 'hesitater' comes from the Latin 'haesitare' (meaning to hesitate or be in doubt), which is a frequentative form of 'haesus' (meaning to stick or cling). The suffix '-er' indicates a person who performs an action. Thus, a hesitater is a person who is in a state of hesitation or doubt.
Think of someone who is 'sticking' ('haesus') to their doubts — that's why a hesitater is someone who hesitates.
