「第六意觸至故名為長」者，釋第二句。第六意識相應觸說名增語。所以稱名為增語者，語是音聲而為無詮表，名有詮表增勝於語，故名增語。又解：此名以語為增上方能詮表，故名增語。又解：增謂增長，由緣名故增長語言。又解：謂由名力令語增勝，故名增語。此名是意識所緣長境，故就所緣名增語觸。增語之觸，依主釋也。所以名為長境者，如眼識但能了青、不了青名，意識了青亦了青名。意識與五識同緣境已，更緣其名，故名為長。

"The sixth, mental contact [...] is therefore termed extensive": this explains the second line. Contact associated with the sixth, mental consciousness, is termed "linguistic designation" (adhivacana). As for why it is named "linguistic designation": speech is sound and does not have the capacity to express, whereas name possesses expression and surpasses speech, hence it is termed "surpassing speech" (adhivacana / linguistic designation). Another explanation: this name takes speech as its predominant condition in order to express, hence it is termed adhivacana. Another explanation: "adhi" means augmentation; due to cognizing names, language is augmented. Another explanation: by the power of names, speech is made superior, hence it is called adhivacana. This name is an extensive object cognized by mental consciousness; therefore, with respect to its object, it is named "linguistic designation contact". "Contact of linguistic designation" is a tatpuruṣa compound. Why is it termed an extensive object? For example, eye-consciousness can only apprehend blue, but not the name of blue, whereas mental consciousness apprehends blue and also apprehends the name of blue. After mental consciousness cognizes the object together with the five consciousnesses, it further cognizes its name; hence it is called "extensive".
