Cross-Linguistic Patterns in Language and Science

In many languages, nouns for objects that are higher in space are marked with a grammatical case that indicates elevation, such as the ablative case in Latin or the locative case in Finnish.

The Sapir-Whorf hypothesis, also known as the linguistic relativity hypothesis, proposes that language and thought are partially determined by each other, meaning that the structure of a language can influence the way its speakers think and perceive the world.

Determiners, such as articles and demonstratives, are a linguistic category that is not found in all languages. Some languages, like Japanese, do not have articles, while others, like English, have both definite and indefinite articles.

Polysemy is the phenomenon in which a word has multiple related meanings, depending on the context in which it is used. For example, the word "bank" can refer to a financial institution, the side of a river, or a long seat.

Yucatec Maya is a Mayan language spoken in Mexico and Belize. It has a complex system of evidentiality, which is a grammatical system that encodes the speaker's source of information. For example, Yucatec Maya has different verb forms to indicate whether the speaker witnessed an event, heard about it from someone else, or inferred it based on evidence.

Linguistic relativity, also known as the Sapir-Whorf hypothesis or the Whorfian hypothesis, is the phenomenon in which the structure of a language influences the way its speakers think and perceive the world.

Spanish is a Romance language that has a grammatical gender system, meaning that nouns are assigned a gender, either masculine or feminine. This gender assignment can affect the way that nouns are used in sentences, such as in the choice of adjectives and articles.

Phonological inventory refers to the limited number of sounds that a language has available to form words. This inventory includes both consonants and vowels, and it can vary significantly from language to language.

Mandarin Chinese is a tonal language, meaning that the pitch of a syllable can change its meaning. There are four main tones in Mandarin Chinese: the first tone is high and level, the second tone rises, the third tone falls and then rises, and the fourth tone falls.

A case system is a grammatical system that marks the different roles that nouns can play in a sentence. For example, in Latin, nouns can be marked with different cases to indicate their role as subject, object, indirect object, or possessive.

English has a system of grammatical number, meaning that nouns can be marked to indicate whether they are singular or plural. This is done using different suffixes, such as "-s" for plural nouns.

A tense system is a grammatical system that marks the time of an event or state. For example, in English, verbs can be marked to indicate whether an event happened in the past, present, or future.

Spanish has a system of grammatical aspect, meaning that verbs can be marked to indicate whether an event is completed, ongoing, or habitual. This is done using different verb forms, such as the preterite and imperfect tenses.

A mood system is a grammatical system that marks the speaker's attitude towards the proposition expressed by the sentence. For example, in English, verbs can be marked to indicate whether the speaker is making a statement, asking a question, or expressing a wish.

English has a system of grammatical voice, meaning that verbs can be marked to indicate whether the subject of the sentence is the actor or the recipient of the action. This is done using different verb forms, such as the active and passive voices.
