Conceit, more rich in matter than in words,
Brags of his substance, not of ornament.
They are but beggars that cannot count their worth;
But my true love is grown to such excess
I cannot sum up half my wealth.
Juliet says it is nice to speak of happiness and love but deeds and actions are more important "richer" than the words used to describe it:
"Conceit, more rich in matter than in words,
Brags of his substance, not of ornament."
She says beggars care about the little they have (they can count it) while the rich merely take their wealth for granted and do not value it. Juliet ends with her love being so huge, she could not begin to count it even if she wanted to. Juliet is kind of challenging Romeo to prove himself rather than use flattering language which comes so easily to him.
