 Extensional prefixes have compositional, transparent meanings: unlike derivational affixes in many natlangs, the combinations involving roots and extensional prefixes do not require being learnt separately from the meaning of their components; the meaning of such combinations can always be derived from the meanings of the components without any need to looking up combinations in a dictionary.  
 
+Extensional prefixes cover a wide range of uses and meanings, even including pronominal references like “me”, “you” and so on. In actuality, Nahaıwa lacks standalone pronoun words. When it is wished to use an extensional prefix (such as a pronominal) as a complete word, a dummy root such as ⟪-yá⟫ can be used.
+
 Extensional prefixes that have fused with the root into a lexicalized combination with an opaque meaning always become part of the root/base itself, i.e. they are no longer located in the Extension slot (that is, the position of the prominent syllable in the word, which always appear on the first syllable of the lexicalized, semantically opaque part of the word, namely the word's root or base, is shifted leftwards so as to engulf any former extensional prefix that would have thusly formed an opaque combination with the root, transforming that former prefix into an element of the root itself, within the Root slot).  
 
 Extensional prefixes have shape -C?CV(yV)-: they begin with a single consonant or a consonant cluster followed by a vowel, possibly elongated with a second syllable starting with the ⟪y⟫ semivowel. If they begin with a cluster, the first consonant of the cluster may be phonetically part of the coda of the preceding syllable (the cluster then crosses the syllable boundary): for example, ⟪nta⟫ is a valid extensional prefix, with the ⟪n⟫ part belonging to the preceding syllable.

 Modifies one slot of the stem (sort of removes one and adds one); the vowel part of the affix, represented by the symbol ⟪◈⟫ below, is variable and represents the “Inner Case” identifying which slot is selected by the affix; the meaning of the slot is modified, but this suffix type does not bind the extensional case, it just reuses the modified cases. The resulting valency and case set of the predicate is unchanged.  
 With unary bases, the vowel is ⟪a⟫ (Intransitive Inner Case).

+## Pronominals
+
+As mentioned earlier, Nahaıwa pronominals are expressed as extensional prefixes, more specifically of type −+, with a variable inner case vowel.
+
+Here are some of the main pronominals:
+
+| Form | Meaning |
+|------|---------|
+| n◈   | I/me (singular speaker, or rarely, multiple authors of a same utterance, as in written joint work) |
+| k◈   | you (addressee, either singular or plural, never including absent third parties) |
+| ŋk◈  | me + you |
+| θ◈   | you know what/who (contextually ascertainable 3rd person) |
+| nt◈  | that which I am pointing to or looking at (pointing demonstrative) |
+| t◈   | resumptive pronominal (refers to the antecedent in relative clauses) |
+| tʼ◈  | monovalent lambda pronominal (covers the interrogative “what” among other uses) |
+
+The plural “we” has no dedicated pronominal, but can be expressed by adding the associative plural extension ⟪-nθ◈-⟫ right after ⟪-n◈-⟫, with the same inner case vowel: ⟪-n◈nθ◈-⟫ (“me and co.”).
+
+They all can be used as full words by combinging the with the dummy root ⟪-yá⟫, ⟪[NTR] is a thing, is something⟫, with the Intransitive inner case vowel ⟪-a-⟫: ⟪-nayá⟫ ≍ ⟪[NTR] is me⟫.
