gotta
hafta
oughta
If speakers actually use the full forms, however, you must add an underscore, as in
ought_to
got_to
have_to
In a few cases, you will want two separate words, as in "I got to the lake before noon".
These changes do not affect gonna, shoulda, coulda, wanna, sposta, or dunno, which were already being processed fine by v-clit.cut and v-modal.cut.
