The affix ṇamul comes after the bandh 'to bind' when a word so formed denotes an appellative.,
Thus क्रौञ्चबन्धं बध्नाति 'he binds in the manner called krauncha-bandhan or 'heron-knot'. मयूरिकाबन्धं बध्नाति or बद्धः 'he binds or is bound in a 'peacock-knot'. अट्टालिकाबन्धं बद्धः 'bound in a knot called attalika-bandhan'.
All the above, krauncha-bandhan &c. are names of various sorts of 'bonds or knots'. The rule (III. 4. 46.) also applies here.,
