An iamb is when a word's syllables are unstressed, then stressed, then unstressed, etc. An example of an iamb on this list is "inspire." Notice how "in-" is said softly/lowly, "-spi-" is said sharply/louder, and finally the "yer" ending is said quietly. The word "inscribe" also follows this.
A trochee is the reverse of an iamb; it is a word whose syllables are stressed, then unstressed, etc. An example of a trochee on this list is "happy." The "ha-" part of the word is said harshly, whereas the ending "-ppy" is said noticeably softer. Trochee itself is an example of a trochee.
An anapest is two unstressed syllables followed by a stressed syllable. An example of an anapest on this list is "understand," I believe, but anapests were never my area of expertise. Try to look into that one a bit more if you can!
A dactyl is the opposite of an anapest; it is two stressed syllables followed by a stressed syllable. An example of a dactyl on this list is "buffalo." Notice how "buff" is said louder/harsher than the following "uh" and "lo" sounds.
A spondee is a word with two stressed syllables. An example of a spondee on this list is "mayday," where both "may" and "day" are pronounced with the same amount of harshness/stress.
My advice for the other words on this list is to say them aloud. Listen if one syllable sounds louder or quieter than other--or, in the case of a spondee, if both syllables are of equal harshness!
