is not a ‘normal’ strong verb stem. On account of its marginal status, it will be
disregarded in the following.
Finally, the verb
KOMMENw
is usually assigned to the fourth class of
strong verbs (gradation e-a-o, cf.
NEHMENW)
although its ‘principal parts’ are
kommen-kam-gekommen
,34
Its base vocalism would have to be regarded as
deviant. By the present synchronic approach, however, the stem
KOMML
shows
ordinary o-ablaut (
komm—*kam): it has one (and only one) ablaut form
(kam),
which is an A-form, and there is short—»long-alternation. However,
KOMML
is
the only stem that shows U—»A-alternation.35

Functions of ablaut
3.1 Functional types
It is customary to distinguish what may be called functional types of stem
forms. Usually, these are referred to as ‘present stem’, ‘past stem’ and ‘parti-
ciple stem’. In terms of the present approach, the differentiation of functional
types constitutes a classification of stem forms (i.e., forms of stem lexemes),
namely, a classification that accounts for the stem forms’ functions. Of course,
these are related to the (functional) categorisations of the forms of verbs that
contain the stem forms in question (cf. Lieb 1983: Section 11.3, 1992).
In addition to the named three primary types there are the so-called ‘sec-
ondary present tense stems’ and ‘secondary past tense stems’. The differentia-
tion of primary and secondary stem forms is a matter of subclassifying the sets
of present and past tense stem forms, respectively. The received terminology
(primary-secondary) obviously reflects the assumption that secondary forms
are derived from their primary counter-parts. It also points to the observation
that this subdifferentiation does not always apply, that is, there are stems such
that one or both secondary forms are missing. No doubt, the primary-
secondary-differentiation imposes an order of markedness on functional types.
An order in terms of markedness may also be established among primary
stem forms. The traditional differentiation of three ‘primary stems’ tends to
give the impression that these three types were on an equal footing, but they 14 15

German; see, e.g., Curme (1922: 311).

patterns.

are positively not.36 Stem forms must not be classified into three types of equal
rank; such a classification would be inhomogeneous, a mixing of two criteria
that interact in the differentiation of the three functional types, viz. tense and
fmitude. The traditional three-element classification should be replaced by a
system of two classifications: a basic classification according to tense as
proposed by Lieb (1978) and a sub-classification in terms of fmitude.37 38
I assume, then, a classification into non-past and past forms as a first
functional classification on the set of stem forms of strong verbs.3X This is in
accordance with a traditional line of thought that ranks past participles — as
the name says — among past forms. The set of past tense forms is subclassi-
fied according to fmitude: this subclassification sets apart stem forms that
occur in finite past verb forms (the ‘primary and secondary past tense stems’)
from those that occur in non-finite (or ‘infinite’) past verb forms (the latter
being tradition’s ‘participle stems’, of course). In its turn, the prima-
ry/secondary-distinction imposes a subclassification on the set of finite past
tense stem forms in terms of mood. Accordingly, I distinguish between finite
past non-subjunctive forms (‘primary past stems’) and finite past subjunctive
forms (‘secondary past stems’). To complete the classification system the
traditional distinction between ‘primary and secondary present tense stems’
would have to be accounted for. However, as ablaut concerns the formation of
past forms only, this part of the classification system may be left without
analysis for purposes of the present investigation.39
The proposed system of classifications may be presented by means of a
classification tree that is given in Figure
1
(next page). The basic set
stro n g
is
the set of forms of stems of strong verbs;
tense, fmitude and
mood are the
names of the three classifications introduced above. Names of classes are
obvious abbreviations. The subclassification of non-past forms is left out. For
36 Compare, for instance, Augst (1975: 251), who assumes that in Modem German a
formerly given discrepancy between four ‘ablaut grades’ and three ‘tense grades’ (“4
Ablaut- aber 3 Tempusstufen”) has been remedied. This would seem to imply that the three
‘primary stems’ are differentiated solely in terms of tense (cf. 266: “[...] wird der Vokal-
wechsel allein mit der Tempusunterscheidung belastet.”).
17 Cf. also Halle & Marantz (1993), who assume two features, [± past] and [± participle],
and see Wunderlich & Fabri (1995) on the feature [± AGR]. For discussion of the non-
morphemic character of notions such as ‘past stem’ see Blevins (2003).
38 Significantly, in the case of ‘tense stems’ of weak verbs, this distinction is the only one
that applies, cf. lob (non-past) vs. lobt (past).
39 Lieb (1978: 206) distinguishes three types of present tense stem forms because there are
two varieties of ‘secondary present tense stems’; those that show umlaut are restricted to
the 2nd/3rd person singular present indicative while those that show //e-alternation are used
with imperatives in addition.
