Personification is a figure of speech, in which a thing, idea or animal is given human qualities and/or abilities. As a consequence, it created meaning in giving the non-human object “life” making us feeling that it has the ability of acting as a human being.
In these lines, the imagery of “time” is personified in such a way that it affects the poem because it (“time”) stands as a “thing” that has the ability of moving, changing (“turning”) and at the same it allows or gives birth to morning songs. (Perhaps it may also prohibit or become an obstacle for certain things).
