Etymology: "Uptightest" is simply the superlative of "uptight," so its history is that of the adjective it modifies. Its form follows the ordinary English pattern of adding "-est" to a short adjective, giving the sense of the most tense, constrained, or formal of any group being compared. The base word "uptight" is a compound of "up" and "tight," and it is the "tight" half that carries the core idea. Something tight is drawn taut and held firmly in place, so a person described as uptight is figuratively wound up, with nerves stretched and manner held rigidly in check. The superlative therefore picks out whoever seems the most strained or stiffly proper among the people or situations being compared.
