 First-order indexicality can be defined as the first level of pragmatic meaning that is drawn from an utterance.For example, instances of deference indexicality such as the variation between informal "Tu" and the more formal "Vous" in French (See T/V deference indexes) indicate a speaker/addressee communicative relationship built upon the values of 'power' and 'solidarity' possessed by the interlocutors.When a speaker addresses somebody using the V form instead of the T form, they index (via first-order indexicality) their understanding of the need for deference to the addressee.
