(Noun) + 型(がた)Model, Type, Pattern, Kind, Shape, Size(d)

型(がた), or sometimes 形(がた), are two kanji that are often used as a suffix, to identify that something is 'shaped', or 'sized' according to (A). The primary reading of both of these kanji is かた, but becomes がた due to 連濁(れんだく) (sound changes due to conjugation). 型(がた) can be attached directly to the end of nouns, or to い-Adjectives. Occasionally, 型(かた) will be used after the case marking particle の. In these cases, because it is connected to の, and not directly to the noun, it will be read as かた, not がた.

Although there are two different kanji that can be used in this expression, 型(がた) will be used far more frequently than 形(がた). This is primarily due to the base meanings that these kanji have. Those meanings are as follows:

型(がた) - Form (in regard to design, pattern, type, or model).

形(がた) - Shape (in regard to physical shapes only. Square, rectangle, triangle, etc).

Due to this, 型(がた) is used when describing any form/pattern that is abstract, while 形(がた) is primarily only used for describing very basic (visible) shapes.

Caution

Occasionally, 型(がた) may be read as 型(けい), the 音(おん)読(よ)み (Chinese reading) of 型(けい). This is primarily when it is paired with other words that also use their 音(おん)読(よ)み, or when it is not acting as a suffix, but part of a set word.
