Mattie noticed a lump on the surface of her right oxter and was concerned that it might be a sign of breast cancer; so, she went to Dr. Schmidt to have it checked.2. Etymology: from Old English ohsta or oxta, "armpit". The origin of oxter is not from Latin; however, it is indirectly related to Latin axilla, "armpit".
The word oxter is used in certain areas of the world (Scotland, Ireland, Northern England), and it serves as a reminder that there are many other local and colloquial names for parts of the human anatomy.
Muriel oxtered or folded her arms around her newly-born baby, Jimmy, when she left the hospital.
