From my basic lay understanding of non-polysynthetic linguistics (and this answer), a word may be either:

  • #1. A single root (or "stem" or "base") morpheme; or
  • #2. One or more affixes combined with a root.

Is there a more specific term for a word of the #2 type? For example, the word "enjoy" would be an instance of that term, but the word "joy" would not.

An existing english.stackexchange question asks almost the same thing, but its answer is that #1 is a root and #2 is a root plus affix(es), which doesn't quite answer my question. I'm looking for a term that specifically means #2.

    Derivation or inflection, I'd say – Luke Sawczak Mar 18 '18 at 18:55

    I think this depends on the theoretical framework you're working under or, in some cases, the researcher you're talking to. For instance, I understand base to be a general term for roots and stems, a root to be a free morpheme with no affixation, and a stem to be a root with any combination of affixes attached. Another linguist may very well think of these terms differently, especially if they're working under a different theoretical framework. – joshisanonymous Mar 19 '18 at 0:19

There are appropriate adjectives, but not nouns: "joy" is monomorphemic, "enjoy" is polymorphemic (under a liberal interpretation of English morphology). Other words like derivation, inflection etc. refer to the morphological process, but not the product of a morphological process (or its lack, in the case of an underived / monomorphemic root). Also note that an answer from English SE is likely to only consider the kinds of morphology found in English, and in many languages, roots are not even words.

There are several common terms in use, e.g. monomorphemic or simplex words, and polymorphemic or complex words; cf. the screenshot below from The Oxford Handbook of the Word (from the article written by Geert Booij):

Incidentally, I would analyze enjoy as a simplex word, at least synchronically in (Modern) English; see the screenshot above.

  • Also enlighten, lighten, redden, blacken, and soften? – jlawler Mar 19 '18 at 19:34
  • @jlawler redden, blacken, soften: ADJ+en, suffix; lighten (and its derivative enlighten): N+en, suffix. – Alex B. Mar 19 '18 at 20:21
  • The causative/inchoative prefix en- and the causative/inchoative suffix -en are no longer productive. There are lots of -en words, as you note, but there are lots of en- words, too. Here's 18 that start with em-: embalm embargo embark embattled embed embellish embezzle embitter emblazon embody embolden emboss embrace embrasure embroider embroil employ empower. There isn't room for the 51 others that start with en-, like ensure, enforce, engrave, enlist, enroll, and enslave. – jlawler Mar 20 '18 at 2:24
  • @jlawler some of the 51 words you mention are irrelevant, e.g. ensure (en+ADJ); some are somewhat questionable, e.g. OED says enforce and enroll were borrowed as such etc. – Alex B. Mar 20 '18 at 3:59
  • @jlawler also note that I originally wrote "synchronically in (Modern) English" in my answer - cf. yours "The causative/inchoative prefix en- and the causative/inchoative suffix -en are no longer productive" [emphasis mine - A.B.]. – Alex B. Mar 20 '18 at 4:01

There is a lot of terminology floating around that.

First, the basics: There are word forms occurring in real life. A word form belongs to a lemma that is a canonical word form relating to some other forms (e.g., for the lemma "have" there are the word forms "have", "having", "has", and "had"). Then, there is a stem that is generated off a word form by cutting some affixes. All those terms relate to basic morphology (there is not a lot of it left in English, other languages have a much richer morphology). Note that one lemma can have several (more or less obviously) related stems, like Latin scribere, scribo, scripsi, scriptum exhibiting three stems (present, perfect, and supine stem).

Morphemes come into play when you consider semantics. Derivational morphology and composition are means of creating word forms (and even stems) containing more than one morpheme. A word form containing only one morpheme is called monomorphemic. With two morphemes, it is dimorphemic and so on. As an opposite of monomorphemic, the term polymorphemic can be used.

You can also put your focus on word formation, than you find that a word is suffixed (only rarely suffigated, has a suffix attached), prefixed (with a prefix), infixed (with an infix), or just affixed (with an unspecified affix).

  • imho bimorphemic is more common than dimorphemic in morphological research. – Alex B. Mar 18 '18 at 20:58

    Interesting forms, the ones I'm familiar with are: suffixed, prefixed, infixed, affixed. – Gaston Ümlaut Mar 18 '18 at 22:54
  • @GastonÜmlaut you're absolutely right. All those words, suffigated etc. are extremely rare in English, unlike in German or Russian linguistics. – Alex B. Mar 19 '18 at 1:49

    @AlexB.: I thought about bimorphemic, too, but than I decided for dimorphemic because it is a Greek-Greek formation while bimorphemic is Latin-Greek. – jk - Reinstate Monica Mar 19 '18 at 7:07

    IMHO this answer covers it but is just missing the actual string polymorphemic. – Adam Bittlingmayer Mar 20 '18 at 11:57

'Derived words' are also used, especially in the context of functional linguistics. In French, we don't use 'complex words' for the words su/pr/in-ffixed, rather we used 'les mots dérivés'. You'll find different terminology associated with these, but the standard assumption is that 'affected' 'marked' or 'derived' are always the opposite of 'basic form' 'root form', etc.


Affixation (def), "the result of adding an affix to a root word" (WordNet)

    Affixation refers to the process, not the resulting word. – curiousdannii Mar 19 '18 at 2:43

    You could posit "affixated" as an adjective which describes the result. I wouldn't, though... – tripleee Mar 19 '18 at 10:57
  • @curiousdannii If affixation referred to the process, the definition would have said "the act of", "the process of", etc. Instead, the definition states the "result of", indicating that it is in fact, the result, not the process. – jeff schneider Mar 19 '18 at 11:48
  • @jeffschneider Not all definitions are accurate. If you can find some actual examples of linguists using "affixation" in this way that would be a different matter. – curiousdannii Mar 19 '18 at 11:56

    I personally use 'affixation' for the process and the result. – Jeremy Needle Mar 20 '18 at 13:20
