After the word eka comes also the affix ākinic (ākin) (the word retaining its denotation) when the sense is 'without a companion'.,
By the word च, the affix कन् and the elision लुक् also take effect: the elision being of कन् or आकिनिच् ॥ Thus एकाकिन् (nom. एकाकी), एककः or एकः ॥ By using असहाय, it is indicated that the word एक here is not a numeral meaning 'one', but a noun meaning 'alone'. एकोऽन्यार्थे प्रधाने च, प्रथमे, केवले तथा ॥ साधारणे, समानेऽल्पे, संख्यायां च प्रयुज्यते ॥ So that this word will have dual एकाकिनौ, and the plural एकाकिनः ॥,
