Baste
late 15th century: of unknown origin.
wiktionary
Late Middle English, from Old French bastir(“build, construct, sew up (a garment)”).
Middle English basten, of uncertain etymon, possibly from Old French basser(“moisten, soak”), from bacin(“basin”).
Perhaps from the cookery sense of baste or from some Scandinavian etymon. Compare Old Norse beysta(“to beat, thresh”) (whence Danish børste(“to beat up”)). Compare also Swedish basa(“to beat with a rod, to flog”) and Swedish bösta(“to thump”). Might be related French bâton (formerly baston), which means stick (English baton comes from bâton) ; see also French bastonnade, the act of beating with a stick.

baste (v.1)
"sew together loosely," c. 1400, from Old French bastir "build, construct, sew up (a garment), baste, make, prepare, arrange" (12c., Modern French bâtir "to build"), probably from Frankish or some other Germanic source, from Proto-Germanic *bastjan "join together with bast" (source also of Old High German besten; see bast).
baste (v.2)
"to soak (cooking meat) in gravy or molten fat, moisten," late 14c., of unknown origin, possibly from Old French basser "to moisten, soak," from bassin "basin" (see basin). Related: Basted; basting.
baste (v.3)
"beat with a stick, thrash," 1530s, perhaps from the cookery sense of baste (v.2) or from Old Norse beysta "to beat" or a similar Scandinavian source (such as Swedish basa "to beat, flog," bösta "to thump"), from Proto-Germanic *baut-sti-, from PIE root *bhau- "to strike."
