The choice of delimiter for zoi is both a stylist and informational choice. The only requirement is that it not a word that appears in the quoted text. The following delimiters can be used to communicate specific intent:
| .fanva. | This zoi quote is a translation of some preceding material. |
| .glic. | A variation of .gy. |
| .gy. | This zoi quote is quoting English text. |
| .kliz. | This zoi delimiter suggests the user is quoting Klingon. Klingon writing has no k or z, and Klingon speech has nothing confusable for z. As well, .kliz. is reminiscent of the language name. |
| .url. | This zoi quote is quoting a url. |
| .xlali. | This guard word suggests (but does not require that) the speaker doesn't like the quotation. |
| .xy. | A good guard word for English as the letter combination is rare and it is a non-English phoneme. It may sound like "uh huh," however. |
A long text should really use a long and unlikely word as a delimiter, to remove the possibility of it appearing in the text.
You are limited to using Lojban words as your delimiter in zoi. Punctuation, like "" or <> are not valid lojban words. If you use punctuation in a zoi quote, you may be understood, you won't be speaking proper Lojban.
