I was wondering about something called the poetic license... Can I use "his" instead of "its" when I refer to something else other than the human in poetry?
Generally not unless you're writing in Middle English; or you're using personification. If you are attributing human characteristics to something, say, the sun, you can write, "His bright face rises over the hills ... ", but you need a reason to do this, and it generally comes in the context of an extended metaphor.
Do you have an example in mind?
Hi dear,
Nice to hear the answer from you.
Yes I have an example and in fact the original writer here gives personification in his poem to "the violet".
"The Violet"
His heart is the joy
while grief
is a bed of his.
