"To his coy mistress" is a metaphysical poem written by Andrew Marwell. It is organized into three stanzas the first consists of 20 lines (10 rhyming couplet), the second of 12 lines (6 rhyming couplet) and the last one of 14 lines (7 rhyming couplet).

The register used is high, because the speaking voice is totally caught by a lady and he speaks to her.
In addition throughout the first stanza he uses the conditional tense because he talks about something that it is not real.

1. Had we but world enough, and time: in the first line the words order is altered. The line seems to make reference to an if-clause, but it does not express an hypothesis. As a matter of fact the speaking voice would say: if we had so much space and time we could spend time together, but it is impossible. However, since it is an imaginary-scene on the present, the if-clause is justified.
The word "world" refers to space on earth, so a not eternal place, instead "but" emphasizes the impossibility of the situation.

2. This coyness, Lady, were no crime: the speaking voice refers to coyness of a specific woman( the Lady whom he makes reference), in fact he uses "this". To him coyness is a crime and therefore she is guilty. The reason of that are explained in the previous line: coyness is a crime because mortal time is not eternal and space as well. In addition they disregard the mortal nature of lovers.

3. We would sit down and think which way: the speaking voice says what he would do if the time were immoral: he would sit down with her (that means that he could take a break) and they would think to a possible way (to pass their time)... the line presents a run- on- line in order to carry faster on reading. Moreover there is also an alliteration of "w" which marks the hypothesis.

4. To walk and pass our long love's day: the previous line is ended: the way which the speaking voice refers to, is that of how passing their time full of love. Of course, the meaning of the line is ironical, because human being is finite.

5. Thou by the Indian Ganges' side: now he starts an exemplification of how they would probably pass their time by using another run- on- line and by making reference to a semantic field of religion ( the register is high). Especially in the fifth line he refers to the Indian Ganges' side, which was a sacred river (it gives an exotic atmosphere to the scene) . "Thou" is the archaic form of "you".

6. Shouldst rubies find: I by the tide: he doesn't refers randomly to rubies. As a matter of fact rubies are precious stones as the woman whom the poem is addressed.

7. Of Humber would complain. I would: a comparison between her greatness and him is made. As a matter of fact she should find rubies by the Indian Ganges ‘side, instead he would complain near the Humber (English river) because he would miss her and Ganges in comparison with Humber is bigger and more important.--> difference between her greatness and him.
This line presents a run-on-line as well.

8. Love you ten years before the Flood: the speaking voice declares distinctly his love by saying that his love could also be so innate that he would love her ten years before the Flood. That is another reference to biblical events.

9. - 10. And you should, if you please, refuse/ Till the conversion of the Jews: it means that if the time were eternal, she could be coy until the conversation of the Jews, so forever( he refers to religious semantic field again). Of course it is an ironical statement, because to him coyness is " a crime".
