For example, the word "about" would be written as "a'bout" to indicate that the stress is on the first syllable.
Here are some other examples:
* "re'cord" (stress on the first syllable)
* "con'duct" (stress on the first syllable)
* "pre'sent" (stress on the first syllable)
* "de'scribe" (stress on the first syllable)
Note that the stress mark is not always used in written English, especially in informal writing. However, it can be helpful to use the stress mark when you want to indicate pronunciation or clarify the meaning of a word.
