Explanation

The "meter" of a poem just describes the pattern (if there is one) of stressed and unstressed syllables in each line—in other words, the rhythm of the words. "Iambic" describes one particular type of pattern that happens to be particularly common in English poetry. An iamb is a two-syllable pair, consisting of an unstressed syllable that's followed by a stressed syllable. (If you say "allow" out loud, you'll hear an iamb. It sounds like da-DUM.)
