Constituent insertion differs from equivalence-based switching in that word order<br />

<strong>constraints</strong> across switch boundaries need not be respected <strong>for</strong> those elements<br />

eligible to be inserted. Switching at equivalence sites is <strong>the</strong> only mechanism<br />

which does not involve insertion <strong>of</strong> material from one language into a sentence <strong>of</strong><br />

<strong>the</strong> o<strong>the</strong>r – once a switch occurs, <strong>the</strong> rest <strong>of</strong> <strong>the</strong> sentence may continue in a new<br />

language (although fur<strong>the</strong>r switches are possible), whereas <strong>the</strong> o<strong>the</strong>r mechanisms<br />

generally require a return to <strong>the</strong> original language immediately after <strong>the</strong> nonce<br />

loan, inserted constituent, or flagged switch.<br />

In summary, Poplack (1990: 37-38) argues that “intrasentential switching may<br />

occur at equivalence sites (where switch permissible switch points are constrained<br />

by word order homologies between switched constituents), or, more rarely,<br />

consist <strong>of</strong> constituent insertion (where word order <strong>constraints</strong> across switch<br />

boundaries need not be respected <strong>for</strong> constituents eligible <strong>for</strong> insertion)”.<br />

Lipski (1977) (cited in Myers-Scotton, 1993b), who studied Spanish/English<br />

codeswitching, extends on this, arguing that <strong>the</strong> syntaxes may be different be<strong>for</strong>e<br />

<strong>the</strong> switch, but must be alike <strong>for</strong> <strong>the</strong> portion that is switched. Here again, this can<br />

only be applicable where <strong>the</strong> two languages involved belong to <strong>the</strong> same language<br />

family <strong>and</strong> share common <strong>grammatical</strong> <strong>and</strong> syntactic features.<br />

All <strong>the</strong> above <strong>constraints</strong> deal with word order equivalence as constraint on<br />

codeswitching. Ano<strong>the</strong>r major constraint that is important to consider is one<br />

which deals with <strong>the</strong> morphology <strong>of</strong> <strong>the</strong> languages involved in codeswitching,<br />

referred to as <strong>the</strong> free-morpheme constraint. Poplack (1980) (cited in Myers-<br />

Scotton, 1993b), argues that codes can be switched after any constituent, as long<br />

as <strong>the</strong> constituent is not a bound morpheme. This means that only free morphs<br />

may be switched <strong>and</strong> that a single, multi-morphemic word may not consist <strong>of</strong><br />

morphs from different languages. In o<strong>the</strong>r words, switching is not allowed if it<br />

results in a word having different morphemes from different languages. This<br />

constraint, <strong>the</strong>re<strong>for</strong>e, deals with inflection, plural markers, tense, adjectival<br />

endings, among o<strong>the</strong>rs as <strong>the</strong>se have to be indicated in a single language. Simply<br />

stated, <strong>the</strong>se elements have to correspond with <strong>the</strong> word which <strong>the</strong>y modify.<br />
