In linguistics, the Indo-European ablaut is a system of apophony in the Proto-Indo-European language (PIE).
In the Germanic languages, weak verbs are by far the largest group of verbs, and are therefore often regarded as the norm. They are distinguished from the Germanic strong verbs by the fact that their past tense form is marked by an inflection containing a, , or sound rather than by changing the verb's root vowel.
In Indo-European studies, a thematic vowel or theme vowel is the vowel *e or *o from ablaut placed before the ending of a Proto-Indo-European (PIE) word. Nouns, adjectives, and verbs in the Indo-European languages with this vowel are thematic, and those without it are athematic. Used more generally, a thematic vowel is any vowel found at the end of the stem of a word.
Proto-Germanic is the reconstructed proto-language of the Germanic branch of the Indo-European languages.
The Germanic language family is one of the language groups that resulted from the breakup of Proto-Indo-European (PIE). It in turn divided into North, West and East Germanic groups, and ultimately produced a large group of mediaeval and modern languages, most importantly: Danish, Norwegian, and Swedish (North); English, Dutch and German (West); and Gothic.
The verb go is an irregular verb in the English language. It has a wide range of uses; its basic meaning is "to move from one place to another". Apart from the copular verb be, the verb go is the only English verb to have a suppletive past tense, namely went.
In linguistics, a word stem is a part of a word responsible for its lexical meaning. Typically, a stem remains unmodified during inflection with few exceptions due to apophony
A feature common to all Indo-European languages is the presence of a verb corresponding to the English verb to be.
Proto-Celtic, or Common Celtic, is the hypothetical ancestral proto-language of all known Celtic languages, and a descendant of Proto-Indo-European. It is not attested in writing but has been partly reconstructed through the comparative method. Proto-Celtic is generally thought to have been spoken between 1300 and 800 BC, after which it began to split into different languages. Proto-Celtic is often associated with the Urnfield culture and particularly with the Hallstatt culture. Celtic languages share common features with Italic languages that are not found in other branches of Indo-European, suggesting the possibility of an earlier Italo-Celtic linguistic unity.
This article deals with Japanese equivalents of English adjectives.
In linguistics, a suffix is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns and adjectives, and verb endings, which form the conjugation of verbs. Suffixes can carry grammatical information or lexical information . Inflection changes the grammatical properties of a word within its syntactic category. Derivational suffixes fall into two categories: class-changing derivation and class-maintaining derivation.
Proto-Indo-European nominals include nouns, adjectives, and pronouns. Their grammatical forms and meanings have been reconstructed by modern linguists, based on similarities found across all Indo-European languages. This article discusses nouns and adjectives; Proto-Indo-European pronouns are treated elsewhere.
Early Middle Japanese is a stage of the Japanese language between 794 and 1185, which is known as the Heian period (平安時代). The successor to Old Japanese (上代日本語), it is also known as Late Old Japanese. However, the term "Early Middle Japanese" is preferred, as it is closer to Late Middle Japanese than to Old Japanese.
In linguistic morphology, inflection is a process of word formation in which a word is modified to express different grammatical categories such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness. The inflection of verbs is called conjugation, while the inflection of nouns, adjectives, adverbs, etc. can be called declension.
Old Norse has three categories of verbs and two categories of nouns. Conjugation and declension are carried out by a mix of inflection and two nonconcatenative morphological processes: umlaut, a backness-based alteration to the root vowel; and ablaut, a replacement of the root vowel, in verbs.
The Proto-Italic language is the ancestor of the Italic languages, most notably Latin and its descendants, the Romance languages. It is not directly attested in writing, but has been reconstructed to some degree through the comparative method. Proto-Italic descended from the earlier Proto-Indo-European language.
Historical linguistics has made tentative postulations about and multiple varyingly different reconstructions of Proto-Germanic grammar, as inherited from Proto-Indo-European grammar. All reconstructed forms are marked with an asterisk (*).
Japanese verb conjugation is very regular, as is usual for an agglutinative language, but there are a number of exceptions. The best-known irregular verbs are the common verbs する suru "do" and 来る kuru "come", sometimes categorized as the two Group 3 verbs. As these are the only verbs frequently flagged as significantly irregular, they are sometimes misunderstood to be the only irregular verbs in Japanese. However, there are about a dozen irregular verbs in Japanese, depending on how one counts. The other irregular verbs encountered at the beginning level are ある aru "be (inanimate)" and 行く iku/yuku "go", with the copula behaving similarly to an irregular verb.
Proto-Slavic is the unattested, reconstructed proto-language of all Slavic languages. It represents Slavic speech approximately from the 2nd millennium BC through the 6th century AD. As with most other proto-languages, no attested writings have been found; scholars have reconstructed the language by applying the comparative method to all the attested Slavic languages and by taking into account other Indo-European languages.
A regular verb is any verb whose conjugation follows the typical pattern, or one of the typical patterns, of the language to which it belongs. A verb whose conjugation follows a different pattern is called an irregular verb. This is one instance of the distinction between regular and irregular inflection, which can also apply to other word classes, such as nouns and adjectives.
