Quiz: Remember the definition of mal de mer?
c.1300, from Old French dancier (12c., Modern French danser), of unknown origin, perhaps from Low Frankish *dintjan and akin to Old Frisian dintje "tremble, quiver." A word of uncertain origin but which, through French influence in arts and society, has become the primary word for this activity from Spain to Russia (e.g. Italian danzare, Spanish danzar, Rumanian dansa, Swedish dansa, German tanzen).
In part the loanword from French is used mainly with reference to fashionable dancing while the older native word persists in use with reference to folk-dancing, as definitively Russ. pljasat' vs. tancovat' [Buck].Replaced Old English sealtian, itself a borrowing from Latin saltare "to dance," frequentative of salire "to leap" (see salient (adj.); "dance" words frequently are derived from words meaning "jump, leap"). Related: Danced; dancing.
It is strange, and will, I am sure, appear to my readers almost incredible, that as far as I have ever read, there is no reference that can be identified as containing a clear allusion to dancing in any of our really ancient MS. books.

c.1300, from dance (v.).
found in Judg. 21:21, 23; Ps. 30:11; 149:3; 150:4; Jer. 31:4, 13, etc., as the translation of _hul_, which points to the whirling motion of Oriental sacred dances. It is the rendering of a word (rakad') which means to skip or leap for joy, in Eccl. 3:4; Job 21:11; Isa. 13:21, etc. In the New Testament it is in like manner the translation of different Greek words, circular motion (Luke 15:25); leaping up and down in concert (Matt. 11:17), and by a single person (Matt. 14:6). It is spoken of as symbolical of rejoicing (Eccl. 3:4. Comp. Ps. 30:11; Matt. 11: 17). The Hebrews had their sacred dances expressive of joy and thanksgiving, when the performers were usually females (Ex. 15:20; 1 Sam. 18:6). The ancient dance was very different from that common among Western nations. It was usually the part of the women only (Ex. 15:20; Judg. 11:34; comp. 5:1). Hence the peculiarity of David's conduct in dancing before the ark of the Lord (2 Sam. 6:14). The women took part in it with their timbrels. Michal should, in accordance with the example of Miriam and others, have herself led the female choir, instead of keeping aloof on the occasion and "looking through the window." David led the choir "uncovered", i.e., wearing only the ephod or linen tunic. He thought only of the honour of God, and forgot himself. From being reserved for occasions of religious worship and festivity, it came gradually to be practised in common life on occasions of rejoicing (Jer. 31:4). The sexes among the Jews always danced separately. The daughter of Herodias danced alone (Matt. 14:6).
