仪 is a bound morpheme (b.f.) that cannot stand alone as a word—it always appears as part of a compound. Its meanings fall into three main groups: (1) appearance or bearing (e.g., 仪表 'appearance; meter'); (2) ceremony, etiquette, or rite (e.g., 仪式 'ceremony', 礼仪 'etiquette'); and (3) apparatus or instrument (e.g., 仪器 'instrument'). Though the English glosses also include 'present; gift', that sense is much less common. Learners should recognize 仪 in technical and formal contexts.
