Compound words are a special point of interest with the Integration Hypothesis, as they are further evidence that words contain internal structure. The Integration Hypothesis, analyzes compound words differently compared to previous gradualist theories of language development. As previously mentioned, in the Gradualist Approach, compound words are thought of as part of a proto-syntax stage to the human language. In this proposal of a lexical protolanguage, compounds are developed in the second stage through a combination of single words by a rudimentary recursive n-ary operation that generates flat structures. However, the Integration Hypothesis challenges this belief, claiming that there is evidence to suggest that words are internally complex. In English for example, the word 'unlockable' is ambiguous because of two possible structures within. It can either mean something that is able to be unlocked (unlock-able), or it can mean something that is not lockable (un-lockable). This ambiguity points to two possible hierarchical structures within the word: it cannot have the flat structure posited by the Gradualist Approach. With this evidence, supporters of the Integration Hypothesis argue that these hierarchical structures in words are formed by Merge, where the L component and E component are combined. Thus, Merge is responsible for the formation of compound words and phrases. This discovery leads to the hypothesis that words, compounds, and all linguistic objects of the human language are derived from this integration system, and provides contradictory evidence to the theory of an existence of a protolanguage. In the view of compounds as "living fossils", Jackendoff alleges that the basic structure of compounds does not provide enough information to offer semantic interpretation. Hence, the semantic interpretation must come from pragmatics. However, Nórega and Miyagawa noticed that this claim of dependency on pragmatics is not a property of compound words that is demonstrated in all languages. The example provided by Nórega and Miyagawa is the comparison between English (a Germanic language) and Brazilian Portuguese (a Romance language). English compound nouns can offer a variety of semantic interpretations. For example, the compound noun "car man" can have several possible understandings such as: a man who sells cars, a man who's passionate about cars, a man who repairs cars, a man who drives cars, etc. In comparison, the Brazilian Portuguese compound noun "peixe-espada" translated as "sword fish", only has one understanding of a fish that resembles a sword. Consequently, when looking at the semantic interpretations available of compound words between Germanic languages and Romance languages, the Romance languages have highly restrictive meanings. This finding presents evidence that in fact, compounds contain more sophisticated internal structures than previously thought. Moreover, Nórega and Miyagawa provide further evidence to counteract the claim of a protolanguage through examining exocentric VN compounds. As defined, one of the key components to Merge is the property of being recursive. Therefore, by observing recursion within exocentric VN compounds of Romance languages, this proves that there must be an existence of an internal hierarchical structure which Merge is responsible for combining. In the data collected by Nórega and Miyagawa, they observe recursion occurring in several occasions within different languages. This happens in Catalan, Italian, and Brazilian Portuguese where a new VN compound is created when a nominal exocentric VN compound is the complement of a verb. For example, referring to the Catalan translation of "windshield wipers", [neteja[para-brises]] lit. clean-stop-breeze, we can identify recursion because [para-brises] is the complement of [neteja]. Additionally, we can also note the occurrence of recursion when the noun of a VN compound contains a list of complements. For example, referring to the Italian translation of "rings, earrings, or small jewels holder", [porta[anelli, orecchini o piccoli monili]] lit. carry-rings-earrings-or-small-jewels, there is recursion because of the string of complements [anelli, orecchini o piccoli monili] containing the noun to the verb [porta]. The common claim that compounds are fossils of language often complements the argument that they contain a flat, linear structure. However, Di Sciullo provided experimental evidence to dispute this. With the knowledge that there is asymmetry in the internal structure of exocentric compounds, she uses the experimental results to show that hierarchical complexity effects are observed from processing of NV compounds in English. In her experiment, sentences containing object-verb compounds and sentences containing adjunct-verb compounds were presented to English speakers, who then assessed the acceptability of these sentences. Di Sciullo has noted that previous works have determined adjunct-verb compounds to have more complex structure than object-verb compounds because adjunct-verb compounds require merge to occur several times. In her experiment, there were 10 English speaking participants who evaluated 60 English sentences. The results revealed that the adjunct-verb compounds had a lower acceptability rate and the object-verb compounds had a higher acceptability rate. In other words, the sentences containing the adjunct-verb compounds were viewed as more "ill-formed" than the sentences containing the object-verb compounds. The findings demonstrated that the human brain is sensitive to the internal structures that these compounds contain. Since adjunct-verb compounds contain complex hierarchical structures from the recursive application of Merge, these words are more difficult to decipher and analyze than the object-verb compounds which encompass simpler hierarchical structures. This is evidence that compounds could not have been fossils of a protolanguage without syntax due to their complex internal hierarchical structures.
==== Interactions between E and L components in phrases of human language ==== As previously mentioned, human language is interesting because it necessarily requires elements from both E and L systems - neither can stand alone. Lexical items, or what the Integration Hypothesis refers to as 'roots', are necessary as they refer to things in the world around us. Expression items, that convey information about category or inflection (number, tense, case etc.) are also required to shape the meanings of the roots.
