Can someone help me use iambic pentameter on 2 lines of sonnet 23?
I need to measure any two lines. I would love to measure these two lines,
"As an unperfect actor on the stage,
Who with his fear is put beside his part."
Yes, these two lines are written in iambic pentameter. Basically, an "iamb" is a term that is used to describe one unstressed syllable followed by a stressed syllable, such as when you say the word "again" - it is said as "a-GAIN" with the emphasis on the second syllable, not on the first.
"Penta" means "five", so "iambic pentameter" simply means five iambs, or ten syllables that follow the unstressed-stressed pattern. It is particularly noticeable in everyday speech, but meter is quite important in poetry.
For your two lines, I'll write them with the unstressed words in lower-case letters and the stressed syllables in caps - there should be ten total syllables in each line:
"as AN unPERfect ACtor ON the STAGE,
who WITH his FEAR is PUT beSIDE his PART."
