# Reference the line number in which a (new) word occurred for the first time

I would like to cross-reference the line number in which a word occurred for the first time in some texts. For example, a text is given:

LESSON I
In the traffic court of a large mid-western city, a young
her for driving through a red light. She explained to his
honor that she was a school teacher and requested an imme-

on to her classes. A wild gleam came into the judge's eye.
"You are a school teacher, eh?" said he. "Madam, I shall
realize my lifelong ambition. Sit down at that table and
write 'I went through a red light' five hundred times."


In it, the new word "disposal" occurred in line 5, so the NEW WORDS LIST is given as below:

----------------------------------------------------
1. disposal (L.5)
2. hasten   (L.5)
3. gleam    (L.6)
...
----------------------------------------------------


How to cross-reference such a number?
