===Ambiguous cases===
If "|variety=us" is set, ''herb(s)'' and ''herbal'' are treated as starting with a vowel sound.

* <code><nowiki>"{{a or an|herb}}"</nowiki></code> → "{{a or an|herb}}"
* <code><nowiki>"{{a or an|herb|variety=us}}"</nowiki></code> → "{{a or an|herb|variety=us}}"

Words before which people have not settled on whether to use "a" or "an" are generally not made exceptions, so the general rules apply.

* <code><nowiki>"{{a or an|FAQ}}"</nowiki></code> → "{{a or an|FAQ}}"
* <code><nowiki>"{{a or an|upsilon}}"</nowiki></code> → "{{a or an|upsilon}}"

If the first letter is a non-Latin character, it returns "a" by default.

* <code><nowiki>"{{a or an|あ}}"</nowiki></code> → "{{a or an|あ}}"

If the parameter is not entered, it returns an empty string.

* <code><nowiki>"{{a or an}}"</nowiki></code> → "{{a or an}}"
