Macro-Chibchan is a proposal linking languages of Colombia and Nicaragua. These languages were once included in the Chibchan family

 itself, but were excluded pending further evidence as that family became well established. Kaufman (1990) finds the Chibchan–Misumalpan connection convincing, if as yet unsubstantiated, though Campbell (2000) finds it doubtful.

Constenla (2005) provides 85 forms he proposes display regular correspondence between Lencan, Misumalpan, and Chibchan, a group he calls Lenmichí (Lencan–Misumalpan–Chibchan). He suggests that Chocoan

 may be related as well.

Greenberg proposed a broader conception of Macro-Chibchan, one dismissed by linguists working on the families in question. It included Yanomam, Tarascan, and Cuitlatec

Reconstruction

Vowels

Constenla (2005) reconstructed the vowels of proto-Lenmichian as follows:

	Front Front vowel A front vowel is a type of vowel sound used in some spoken languages. The defining characteristic of a front vowel is that the tongue is positioned as far in front as possible in the mouth without creating a constriction that would be classified as a consonant. Front vowels are sometimes also...	Central Central vowel A central vowel is a type of vowel sound used in some spoken languages. The defining characteristic of a central vowel is that the tongue is positioned halfway between a front vowel and a back vowel...	Back Back vowel A back vowel is a type of vowel sound used in spoken languages. The defining characteristic of a back vowel is that the tongue is positioned as far back as possible in the mouth without creating a constriction that would be classified as a consonant. Back vowels are sometimes also called dark...
High	*i		*u
Mid Mid vowel A mid vowel is a vowel sound used in some spoken languages. The defining characteristic of a mid vowel is that the tongue is positioned mid-way between an open vowel and a close vowel...	*e		*o
Low		*a

There are also a series of nasal vowels.

Consonants

Constenla (2005) reconstructed the following consonant system:

	Bilabial Bilabial consonant In phonetics, a bilabial consonant is a consonant articulated with both lips. The bilabial consonants identified by the International Phonetic Alphabet are:...	Alveolar Alveolar consonant Alveolar consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli of the superior teeth...	Velar Velar consonant Velars are consonants articulated with the back part of the tongue against the soft palate, the back part of the roof of the mouth, known also as the velum)....	Labio- velar	Glottal Glottal consonant Glottal consonants, also called laryngeal consonants, are consonants articulated with the glottis. Many phoneticians consider them, or at least the so-called fricative, to be transitional states of the glottis without a point of articulation as other consonants have; in fact, some do not consider...

Fricative Fricative consonant Fricatives are consonants produced by forcing air through a narrow channel made by placing two articulators close together. These may be the lower lip against the upper teeth, in the case of ; the back of the tongue against the soft palate, in the case of German , the final consonant of Bach; or...		*s			*h
Flap Flap consonant In phonetics, a flap or tap is a type of consonantal sound, which is produced with a single contraction of the muscles so that one articulator is thrown against another.-Contrast with stops and trills:...		*ɾ
Approximant Approximant consonant Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough or with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no...		*l		*w
