Mi ni koi no amarinishikaba shinoburedo hito no shiruran koto zo wabishiki - Shui Wakashu(English Translation & Meaning)

身に恋のあまりにしかば忍ぶれど
人の知るらん事ぞわびしき

Roma-ji: Mi ni koi no amarinishikaba shinoburedo hito no shiruran koto zo wabishiki
English Translation: Since my love has grown
too great for me to contain,
though I hide it well,
how it grieves me that others
must know of it all the same.
Meaning: Since love has overflowed my heart, however I hide it, it grieves me that others must surely know.
Commentary: Book Twelve Love Poems II 738

Headnote: "Topic unknown"
The poem says that since love has overflowed the poet's heart, it grieves him that others must know of it however he hides it. It laments that a love too great to restrain shows itself however one tries to conceal it. From here to 743 follow poems on secret love and its coming to light.

First line, "mi ni koi no," means "love within me."
Second line, "amarinishikaba," means "since it has overflowed," with "ni" perfective, "shika" the perfective form of the past auxiliary "ki," and "ba" expressing cause.
Third line, "shinoburedo," means "though I hide it," with "do" concessive. It shares secret love with the first line of the next poem, 739, "shinobitsutsu."
Fourth line, "hito no shiruran," means "that others must know," with "ran" an auxiliary of present conjecture.
Final line, "koto zo wabishiki," means "is what grieves me," with the binding particle "zo" resolved by the attributive "wabishiki."
