Alliteration and Assonance
"'twixt two" is an example of alliteration because the "t" sound is repeated at the start of both syllables. "'Twixt" is a contracted form of "betwixt," which has one syllable too many to fit the meter.
Irony
The major irony in “On Her Loving Two Equally,” occurs when the speaker realizes the paradox of what it means to love two people equally. Although the speaker might be present with one lover, the other, no matter how close proximally, can never be loved equally at the same time. In some way then, the entire poem is an ironic musing on the impossibility of two equal instances of love.
