However, there are many words with two syllables that are generally unstressed when used in a sentence. Here are some examples:
* Prepositions: about, above, across, among, around, before, behind, below, beside, between, beyond, during, into, onto, through, under, upon, within.
* Conjunctions: and, but, or, for, nor, yet, so, while.
* Articles: a, an, the.
* Pronouns: it, its, them, their.
* Short words: again, alone, along, almost, always, because, before, better, every, never, often, since, still, today, where.
Important points:
* Stress can shift: The stress pattern of a word can change depending on the sentence structure. For example, "about" can be stressed in the phrase "it's all about you".
* Emphasis changes stress: Even in a regular sentence, you might stress a word for emphasis, making it stressed even if it's usually unstressed.
Therefore, it's more accurate to say that these words are *generally* unstressed, but they can be stressed depending on the context.
