To begin, an iamb contains two syllables. This occurs in the word "today" because this is composed of the syllables to/day. Moreover, in an iamb, the first syllable is short or unstressed, while the second one is stressed. This feature can be seen in the word "Today" because the syllable that is stressed or emphasized when the word is pronounced is the second syllable or "day". According to this, today is an example of an iamb. Moreover, other words are not iambs because they do not follow the pattern unstressed/stressed syllable.
