Like a spear, like a sword Drawn most slenderly fine, As bright and as tempered, This lady of mine.
Like the wind, like the waves, Like winged arrows in flight, As merry my love, And as swift in delight.
Like a sigh, like a song, That is plucked from the strings, Like the dawn and the dew And the stirring of wings.
Like a star, like the moon, In her glimmering pride. Like the ghost of a dream To her love denied.
Rather than look at each line in isolation, read each verse as a whole. In each one, the speaker is comparing his lover to something with a metaphorical meaning: a spearhead or a sword - bright and sharp; wind, waves, arrows in flight - quick; a sigh and a song, dawn and dew - something gentle and pleasant; a star and the moon, the ghost of a dream - things that are intangible and bright.
