what does this mean the definition:
three syllables with third stressed: a metrical foot of three syllables with the stress on the third syllable, or of two short syllables followed by a long syllable. The word "unconcerned" and the phrase "up the hill" are anapests.
Poetic "feet" are simply indications of the stress patterns of the syllables of words. Stress, in this sense, refers to which syllables are pronounced more loudly than the others.
When you say "unconcerned," you pronounce three syllables, and the third one is stressed: un-con-CERNED
When you say "up the hill," again you pronounce three syllables, and the third one is stressed: up the HILL
