étirée
Étirée is the feminine form of the past participle étiré, and also an adjective meaning stretched or elongated. It describes objects that have been stretched under tension (for example a rope, fabric, or a muscle after a workout) or more figuratively something extended in time or space. In French grammar, étiré is a regular -er participle; étirée agrees in gender and number with the noun. When used in compound tenses with avoir, the past participle agrees with a preceding direct object; with être, it agrees with the subject (e.g., La corde est étirée; Le tissu a été étiré).
S’étirer is the reflexive form meaning to stretch oneself.
Etymology: étirer derives from tirer (to pull); the development of the form étirer reflects the extension sense
Usage: The term appears in physics or engineering to describe elongation under tension, in textiles to describe
