What part of speech is defined by the suffix -ture?

The suffix -ture is commonly used to form nouns in the English language. Words that end in -ture often represent a state, quality, or process, such as "nature," "picture," or "failure." This suffix is indicative of something that has been formed or created, allowing it to be categorized as a noun. In contrast, verbs typically do not carry the suffix -ture at the end; rather, they may end in -ate or other verb-indicating suffixes. Adjectives often have different suffixes such as -ful or -ous, and pronouns stand alone and do not typically utilize suffixes like -ture. Thus, the presence of the -ture suffix clearly indicates that the word it is attached to is functioning as a noun.
