Source etymology 1

Original entry ↗

Of a peacock or other fowl: to stand or walk stiffly, with the tail erect and spread out. · To walk haughtily or proudly with one's head held high. · To walk across or on (a stage or other place) haughtily or proudly. · Often followed by out: to protuberate or stick out due to being full or swollen; to bulge, to swell.

noun

A step or walk done stiffly and with the head held high, often due to haughtiness or pride; affected dignity in walking. · An instrument for adjusting the pleats of a ruff.

Selected source glosses provide context, not a complete modern definition inventory

The verb is derived from Middle English strouten, struten (“to bulge, swell; to protrude, stick out; to bluster, threaten; to object forcefully; to create a disturbance; to fight; to display one's clothes in a proud or vain manner”) [and other forms], from Old English strūtian (“to project out; stand out stiffly; to exert oneself, struggle”), from Proto-Germanic *strūtōną, *strūtijaną (“to be puffed up, swell”), from Proto-Indo-European *streudʰ- (“rigid, stiff”), from *(s)ter- (“firm; strong; rigid, stiff”). The English word is cognate with Danish strutte (“to bulge, bristle”), Low German strutt (“stiff”), Middle High German striuzen (“to bristle; to ruffle”) (modern German strotzen (“to bristle up”), sträußen (obsolete, except in Alemannic)); and compare Gothic 𐌸𐍂𐌿𐍄𐍃𐍆𐌹𐌻𐌻 (þrutsfill, “leprosy”), Old Norse þrútinn (“swollen”). The noun is derived from the verb. Noun sense 2 (“instrument for adjusting the pleats of a ruff”) appears to be due to a misreading of a 16th-century work which used the word stroout (strouted (“caused (something) to bulge, protrude, or swell; strutted”)).

Source etymology 2

Original entry ↗
noun

A beam or rod providing support. · An act of strutting (“bracing or supporting (something) by a strut or struts (sense 1); attaching diagonally; bending at a sharp angle”); specifically, deviation (of the spoke of a wheel) from the normal position.

verb

To brace or support (something) by a strut or struts; to hold (something) in place or strengthen by a diagonal, transverse, or upright support. · To be attached diagonally or at a slant; also, to be bent at a sharp angle.

Selected source glosses provide context, not a complete modern definition inventory

The origin of sense 1 of the noun (“beam or rod providing support”) is unknown; it is probably ultimately from Proto-Germanic *strūtōną, *strūtijaną (“to be puffed up, swell”): see further at etymology 1. The English word is cognate with Icelandic strútur (“hood jutting out like a horn”), Low German strutt (“rigid, stiff”), Norwegian strut (“nozzle, spout”), Swedish strut (“paper cornet”). The verb is derived from sense 1 of the noun. Sense 2 of the noun (“act of strutting”) is derived from the verb: see above.
