 Invited Talk
Revisiting 'do'
Since our earlier work on the history of periphrastic 'do' (Kroch 
1989), there
have been developments in grammatical analysis and in corpus 
construction that
have improved our understanding of the evolution of English auxiliary 
verb
morphosyntax.  In this talk, I will revisit my 1989 analysis and refine 
it on
the basis of these developments.  Firstly, I will make use of Pollock's 
"split
INFL" analysis to revise my earlier account of the diachronic evolution 
of
'do'-support, using the results of recent work by by Han (2000) and Han 
and
Kroch (2000). In addition, I will revisit the quantitative analysis I
presented earlier in the guise of a comparison of that work, based on
Ellegard's 1953 text sample, with an ongoing study based on the now 
nearly
complete Penn-Helsinki Parsed Corpus of Early Modern English.
