In the poem "The Wife's Lament" What specific words in lines 1-23 help you identify this poem as an elegy?

deeply sorrowing,
my own life’s journey

a friendless exile,

My lord commanded me to live with him here
I had few loved ones or loyal friends
in this country, which causes me grief.
Then I found that my most fitting man
was unfortunate, filled with grief,
concealing his mind, plotting murder
with a smiling face
