Answer:
1. iambic = unstressed/stressed arrangement
2. dactylic = stressed/unstressed/unstressed arrangement
3. trochaic = stressed/unstressed arrangement
4. anapestic = unstressed/unstressed/stressed arrangement
Explanation:
An iamb is a metrical foot that contains two syllables - the first one is unstressed, and the one that follows it is stressed. An example would be:
To strive, to seek, to find, and not to yield. (the bolded syllables are stressed).
Iamb is usually coupled with a pentameter to create iambic pentameter which Shakespeare often used in his poetry and plays.
A dactyl is a metrical foot that contains three syllables - the first one is long (stressed), and it is followed by two short (unstressed) syllables. An example would be:
Just for a handful of silver he left us and...
This is a metrical foot that is most commonly found in the English language.
A trochee is a metrical foot that contains two syllables - the first one is stressed, and it is followed by an unstressed syllable. An example would be:
Ah, distinctly I remember it was in the bleak December
A trochee is a direct opposite of an iamb (being completely different from it).
An anapest is a metrical foot that contains three syllables - the first two are short (unstressed), and they are followed by a long (stressed) syllable. An example would be:
Twas the night before Christmas and all through the house
Just like a trochee is a direct opposite of an iamb, anapest is a direct opposite of a dactyl.
Hope this helps :)
