Intelligibility between languages can be asymmetric, with speakers of one understanding more of the other than speakers of the other understanding the first. When it is relatively symmetric, it is characterized as "mutual". It exists in differing degrees among many related or geographically proximate languages of the world, often in the context of a

A first language, native tongue, native language, mother tongue or L1 is the first language or dialect that a person has been exposed to from birth or within the critical period. In some countries, the term ''native language'' or ''mother ton ...
(L1) typically requires considerable time and effort through study and
practical application if the two languages are not very closely related.
Advanced speakers of a second language typically aim for intelligibility, especially in situations where they work in their second language and the necessity of being understood is high.
However, many groups of languages are partly mutually intelligible, i.e. most speakers of one language find it relatively easy to achieve some degree of understanding in the related language(s). Often the two languages are
genetically related, and they are likely to be similar to each other in

Linguistic distance is the name for the concept of calculating a measurement for how different languages are from one another. The higher the linguistic distance, the lower the mutual intelligibility.
Asymmetric intelligibility
Asymmetric intelligibility refers to two languages that are considered partially mutually intelligible, but where one group of speakers has more difficulty understanding the other language than the other way around. There can be various reasons for this. If, for example, one language is related to another but has simplified its grammar, the speakers of the original language may understand the simplified language, but less vice versa. For example,

use mutual intelligibility as a primary criterion for determining whether two speech varieties represent the same or different languages.
[ In a similar vein, some claim that mutual intelligibility is, ideally at least, the primary criterion separating languages from dialects.
A primary challenge to these positions is that speakers of closely related languages can often communicate with each other effectively if they choose to do so. In the case of transparently cognate languages officially recognized as distinct such as Spanish and Italian, mutual intelligibility is in principle and in practice not binary (simply yes or no), but occurs in varying degrees, subject to numerous variables specific to individual speakers in the context of the communication.
Classifications may also shift for reasons external to the languages themselves. As an example, in the case of a linear ]dialect continuum
A dialect continuum or dialect chain is a series of language varieties spoken across some geographical area such that neighboring varieties are mutually intelligible, but the differences accumulate over distance so that widely separated varie ...
that shades gradually between varieties, where speakers near the center can understand the varieties at both ends with relative ease, but speakers at one end have difficulty understanding the speakers at the other end, the entire chain is often considered a single language. If the central varieties die out and only the varieties at both ends survive, they may then be reclassified as two languages, even though no actual language change has occurred during the time of the loss of the central varieties. In this case, too, however, while mutual intelligibility between speakers of the distant remnant languages may be greatly constrained, it is likely not at the zero level of completely unrelated languages.
In addition, political and social conventions often override considerations of mutual intelligibility in both scientific and non-scientific views. For example, the varieties of Chinese

. French in its spoken form is not mutually intelligible with Spanish, Portuguese, or Italian due to the great phonological changes that it underwent, but it has partial intelligibility with all three in written form because it preserves its writing from Middle French with very few changes. According to phonological studies, French is the Romance language that has distanced itself the most from Latin. Also, the incorporation of some Germanic words in the base lexicon makes it more difficult for speakers of other Romance languages to understand. According to Ethnologue, French has 89% lexical similarity
In linguistics, lexical similarity is a measure of the degree to which the word sets of two given languages are similar. A lexical similarity of 1 (or 100%) would mean a total overlap between vocabularies, whereas 0 means there are no common words. ...

** Many Turkic languages are mutually intelligible to a higher or lower degree, but thorough empirical research is needed to establish the exact levels and patterns of mutual intelligibility between the languages of this linguistic family.
