aslant
Aslant (adv) means In a sloping or slanting direction.
Etymology
The adverb comes from Middle English aslant, aslante ('at an angle, in a curve; from the side; figuratively, deviously'), from on slant ('at an angle, obliquely'). Here on is the preposition on ('above and touching something, on; at a place or position', etc.), from Old English on, ultimately from Proto-Germanic *an ('on, upon; on to'), from Proto-Indo-European *h₂en- ('on, on to'); and slant is the noun slant, slante ('incline, slant'), probably from Old Norse slent, from Proto-Germanic *slintaną ('to slide; to slip'), ultimately from Proto-Indo-European *sleydʰ- ('to slide; to slip; to be slick or slippery'). By surface analysis it can also be read as a- (a prefix meaning 'at; in; on', denoting a condition, manner or state) + slant. The adjective and preposition both derive from the adverb.
