How Do You Spell BLOW MERCY?
Pronunciation: [blˈə͡ʊ mˈɜːsi] (IPA) 
The spelling of the phrase "blow mercy" may seem odd, but it is derived from a Scottish dialect of English. The word "blow" is pronounced as /blɔ/, which means to exert air from the mouth, and "mercy" is pronounced as /ˈmɜrsi/, which means compassion or forgiveness. The phrase most likely originated as a command for someone to blow a horn or trumpet to signal mercy in battle. Although the spelling may confuse modern English speakers, it is a unique expression of language evolution.
