This paper provides an account of the distribution of the forms of ellipsis
called Sluicing, NP-ellipsis and VP-ellipsis. It argues that (i) ellipsis
is a pro-form, (ii) the pro-form is within an H-max, H a functional head, b
y LF, (iii) this functional head has the property of being Discourse-linkin
g, which licenses the empty category in the syntax. Most of the data base i
s taken from English, but the analyses include VP-ellipsis phenomena in Ita
lian and NP-ellipsis in Spanish which have not been discussed within the ge
nerative tradition until now. (C) 2000 Elsevier Science B.V. All rights res
