I am learning English. I have read these two words and according to dictionary there meaning is almost same. but I don't know what is actual difference between them. Please elaborate these words using some sentences. Thanks.
Loathe is a verb meaning
to hate someone or something
From an early age the brothers have loathed each other.
Loath is an adjective meaning
to be unwilling to do something
I'm loath to spend it all at once.
To summarize, the two words are used in different parts of the sentence, and the verb (loathe) expresses a much stronger negative emotion compared to the adjective (loath).
