CC Ādi 16.76

‘śrī’-śabde, ‘lakṣmī’-śabde — eka vastu ukta
punar-ukta-prāya bhāse, nahe punar-ukta
Word for word: 
śrī-śabde — by the word śrī; lakṣmī-śabde — by the word lakṣmī; eka vastu — one thing; ukta — is indicated; punar-ukta-prāya — almost repetition; bhāse — appears; nahe — but actually it is not; punar-ukta — repetition.
Translation: 
“Although the words ‘śrī’ and ‘lakṣmī’ convey the same meaning and are therefore almost redundant, they are nevertheless not redundant.
