In Kansai-ben, ちゃう can be used when negating nouns, originally deriving from ちがう.
Nやない, which corresponds to the standard Nで(は)ない, can be used the same way, but is less common than N^?(と)ちゃう.

Like standard Japanese, particles are tend to be omitted, especially in casual speech. However, there are some differences in the ways that they are dropped in Kansai-ben and standard Japanese.

The final particle わ in Kansai-ben is basically like the よ final particle in standard Japanese.

The Kansai-ben final particles で and ど have a function that draws attention to something that the listener might not know. In addition, they can also be used for assertion, question, admonition, and occasionally warning. These final particles are like よ and ぜ in standard Japanese.

Prefix^? ど can emphasize the meaning of the word, and it is more common in Kansai.
One should be warned that this prefix has a certain rude/older man feel to it and should only be used if one knows what they're doing.

In Kansai-ben, the honorific title さん and ちゃん can be used for non-humans, such as for food or greetings. This usage my originate with the polite words and phrases from court language1.

Looking from standard Japanese to Kansai-ben, there are some differences in the final vowels of the te-form^? and ta-form^? when the verb ends with [au], [ou], or [uu] sounds.

The first case is for verbs where the dictionary form^? is just two characters (かう, すう, etc.). In this case the sound before the う extends (vowel extension).

The second case is for the other verbs. In this case the sound before the う can extend (vowel extension), but not necessarily.

There are some differences between the causative forms of standard Japanese and Kansai-ben. For su-verbs and suru-verbs, whereas the negative causative form is always long form in standard Japanese, the short form can be used in Kansai-ben. This is also true for the short causative passive form in Kansai-ben (while it should not be used in the standard). In general, the causative long form is rarely used in Kansai-ben.

The standard Vてあげる and Vてやる may become Vたげる and Vたる in Kansai-ben.

The standard Vてくれない, when used as a request, may become Vてくれへん and Vてんか in Kansai-ben. Vてんか is a shortened form of Vてくれへん, and may be used more by older people.

The Vてしまう of standard Japanese, when used to indicate completion, can become Vてまう in Kansai-ben

The standard Japanese expression to give or ask for permission, Vてもいい, can become Vてもええ in Kansai-ben. Similarly, The standard Japanese Vてもかまわない can become either Vてもかめへん, Vてもかまへん, or Vてもかまん in Kansai-ben. For the differences between the three, please see the usage notes for かめへん, かまへん, and かまん.

The standard progressive, conditional, or stative Vている may become Vてる or Vとる in Kansai-ben. Vてる obviously derives from Vている, while Vとる derives from Vておる. While originally the latter may have been considered more polite, it is now more about personal taste.

It should be noted that in casual speech, even standard Japanese may drop the い form いる in the Vている form.

Like standard Japanese, Vな is also used in Kansai-ben for strong prohibition. However, instead of the dictionary form^? as in standard Japanese, the stem^? form is used.

While there are several ways to express honorifics in standard Japanese (such as using おVになる／なさる, Vれる／られる, and special honorific words like めしあがる), just adding はる to the verb can be used as an honorific in Kansai-ben.

Vやる and Vよる are used to express a speaker's strong feelings, such as surprise or contempt, when the subject is neither the speaker nor the listener (a third-person subject). There is no such a grammar point in standard Japanese.

Although Kansai-ben has the conditional clause __と__ like in standard Japanese, the negative form Vんと can have a different function depending on the intonation.

While Vんと without a downstep^? is the normal conditional clause, Vんと with a downstep can mean "do not V^?" or "without doing V", similar to Vないで(ください) and Vせずに in standard Japanese.

The standard Japanese sentence ending か(な), used in questions and strong negatives, may become かい(な) in Kansai-ben. かいな is also used as in back-channel^? communication (aizuchi) and imperatives.

In Kansai-ben, the conditional clause (れ)ば is rarely used. Instead, the conditional clause たら is heavily used--to the extent that it is often used in cases where it would be not consider appropriate in standard Japanese.

In Kansai-ben, ねん, てん, ん, のん, and たん are used in queries, asking for reasons, and giving explanations.

The standard sentence endings のだ and んだ may become ねん and てん in Kansai-ben. The main difference between the two is that while ねん is mainly used in the non-past tense, てん is always used in the past tense.

Similarly, the standard sentence ending の may become ん, のん, or たん in Kansai-ben. It should be noted that ん and のん have essentially the same meaning, with the difference decided by region or speaker preference. Again, similar to the above, while ん and のん are used in the non-past tense, たん is only used in the past-tense (the た in たん is considered to be a part in ta-form^? of the verbs, adjectives, and nouns that comes in front of たん).

It should be highlighted that just like their counterparts in standard Japanese, ねん and てん are used to express a more emphatic feeling than ん, のん, and たん.

It should also be noted that the てん mentioned here is not related to the てる／てん of verb conjugation.

The standard Japanese endings __じゃないか, __ではないか, and __じゃん can become __やん, __やんか/やんけ, and __がな respectively in Kansai-ben.
These Kansai sentence endings can also be used in the same way as __んだよ in standard Japanese.
There are many uses for these sentence endings; common ones are confirmation, excuses, accusation, notification, and persuasion. The function changes depending on the situation and tone. The __がな ending is used more often by older people.

Unlike standard Japanese, there are two types of potential form^? depending on the situation: ability potential and situational potential. The ability potential, ようV, is often used with question and negative (the negative form is ようVへん and ようV). The situational potential is the same as in standard Japanese.
