A tat-puruṣa compound ending with the words senā 'army', surā 'wine', chāyā 'shadow', śālā 'house' and niśā 'night', is optionally neuter, with the exception of that which is formed by the particle nañ -- nañ [[2.2.6]], and the karmadhāraya compound.,
As ब्राह्मणसेना, ब्राह्मणसेनम् 'the Brahmana army,' यवसुरम्, यवसुरा 'the barley wine,' कुड्यच्छायम् , कुड्यच्छाया 'the shadow of the wall,' गोशालम्, गोशाला 'the cow house.' श्वनिशम्, श्वनिशा 'to-morrow night.' But असेना 'non-army,' परमसेना 'good army,' the former being negative and the latter karmadharaya compound. For accent see (VI. 2. 14. 123).,
