From Middle English tossen (“to buffet about, agitate, toss; to sift or winnow”), of uncertain origin. Perhaps from Old Norse (compare dialectal Norwegian tossa, dialectal Swedish tossa (“to strew, spread”)), or perhaps from an alteration of Middle English tosen (“to tease, pull apart, shred; to wound, injure”). Compare also Dutch tassen (“to pile or heap up, stack”). The Welsh tos (“a quick jerk”) and tosio (“to jerk, toss”) are probably borrowed from the English.
The verb is transitive and typically takes a direct object; it can also function as a ditransitive verb ('toss someone something').
