Ticklish → The word originates from the Middle English 'tiklish', which is derived from the verb 'tickle' (meaning to touch lightly so as to cause laughter or a reflexive response). The suffix '-ish' indicates a characteristic or quality. Therefore, 'ticklish' describes a person who is sensitive to light touches that provoke laughter or a reflexive reaction.
Imagine someone who is easily made to laugh by a light touch — that's what 'ticklish' means, as it describes a quality of being sensitive to tickling.
