s becomes _r_ in the preterite plurals and past participles of strong
verbs, as in _curon_, _[.g]e.coren_ from _[.c][=e]osan_, _w[=ae]ron_ pl. of
_waes_ (was), and in other formations, such as _hryre_ (fall) from
_hr[=e]osan_.
th becomes _d_ under the same conditions, as in _wurdon_, _[.g]e.worden_
from _weorthan_ (become), _cwaeth_ (quoth), pl. _cw[=ae]don_, _cwide_
(speech) from _cwethan_ (infin.).
r is often transposed, as in _iernan_ (run) from original *_rinnan_ (cp.
the subst. _ryne_), _berstan_ (burst) from *_brestan_, _baerst_ (burst
_pret._) from _braest_, _hors_ (horse) from *_hross_.
The combinations cae-, gae- become _[.c]ea-_, _[.g]ea-_, as in _[.c]eaf_
(chaff) from *_caef_, _s[.c]eal_ (shall) from *_scael_, _[.g]eaf_ (gave) =
*_gaef_ from _[.g]iefan_ (cp. _cwaeth_ from _cwethan_), _[.g]eat_
(gate)--cp. _faet_ (vessel).
g[=ae]- often becomes _[.g][=e]a-_, as in _[.g][=e]afon_ (they gave), with
which compare _cw[=ae]don_ (they said).
ge- becomes _[.g]ie_, as in _[.g]iefan_, _[.g]ieldan_ (pay) from *_gefan_,
*_geldan_--cp. _cwethan_, _delfan_. Not in the prefix _[.g]e-_ and
_[.g][=e]_ (ye).
When g comes before a consonant in inflection, it often becomes _h_, as in
_h[=e] l[=i]ehth_ (he lies) from _l[=e]ogan_ (mentiri).
h after a consonant is dropt when a vowel follows, the preceding vowel
being lengthened, thus _Wealh_ (Welshman) has plural _W[=e]alas_.
