formality. This is especially the case with the pattern sprung for sprang (see also simple
past tense rung, shrunk, sung, sunk, stunk and swum).
Most other differences in the past tense and past participle forms are singular, inci-
dental ones, including the differing pronunciation of the past tense forms ate (BrE /et/,
AmE /e
t/) and shone (BrE /ʃɒn/; AmE /ʃoυn/) or AmE past tense dove and snuck (beside
common dived and sneaked) or BrE quitted, betted and fitted (beside common quit and
bet and AmE fit). AmE also sometimes uses proven and shaven as past participles next
to common proved and shaved. Furthermore, AmE has the past participles beat, shook
and swelled (beside normal beaten, shaken and swollen) in the expressions, to be beat
‘completely exhausted’, all shook up ‘upset’ and to have a swelled head ‘be conceited’.
Slay (itself more common in AmE) has two past tenses, literal, though archaic, slew
‘killed’ and figurative slayed, as in That slayed me ‘caused me to laugh vigorously’.
Get and have Get has two past participle forms in AmE, got and gotten, each used
with a different meaning. Have got is used for possession, obligation or logical necessity
in both varieties (for example: possession, I’ve got a book on that subject; obligation,
you’ve got to read it; logical necessity, it’s got to be interesting). Have got for logical
necessity, familiar in AmE, is apparently a more recent and less widespread phenomenon
in BrE. Have gotten, which does not occur in BrE at all, means ‘receive’, as in I’ve
just gotten a letter from her. In its modal sense have gotten means ‘be able, have the
opportunity’, as in I’ve gotten to do more reading lately. These distinctions must be made
lexically in BrE. In addition, the past form had got is not a real option for expressing
possession in either variety, but it is just barely possible in the modal meaning of
obligation in BrE (e.g. They had got to reply by yesterday).
Do and have Further differences in the ways of expressing possession and obligation
(but also events) involve have. AmE treats have in these uses as a lexical verb and there-
fore uses periphrastic do for negation and inversion; only the perfect auxiliary is an
operator in AmE, which means that only it inverts and negates directly (see 5.1.3).
In BrE this seems to be increasingly the case as well; however, lexical have, especially
in the broad sense of possession, may also be treated as an operator, e.g. I haven’t any
idea; Have you a book on this subject?; or Hadn’t she any news? This use, which is as
good as unknown in AmE, is becoming rarer in BrE, especially in questions and even
more so in past tense use. Note that do-periphrasis is obligatory in both varieties for events
such as having lunch, having a good time, having trouble etc.
Pro-form do A further difference involves do as a pro-form. This is the use of one
of its forms (do, does, did, done, doing) to replace a lexical verb instead of repeating
it, e.g. A: Did you write to the hotel? B: Yes, I have done. This type of construction is
exclusively BrE; in AmE B’s reply would be: Yes, I have or Yes, I have done so, both of
which are also possible in BrE.
Modal auxiliaries Other differences between AmE and BrE in the area of the verb
concern the frequencies of the modal verbs. Should, shall, ought to, dare, need and must,
all of which are relatively infrequent in BrE, are even more so in AmE. Dare and need,
furthermore, are more likely to be used as blends between operators and lexical verbs
in AmE. This means that they will use do-periphrasis, but an unmarked infinitive, e.g.
