part of speech แปลว่า

"PARTS OF SPEECH. There are ten parts of speech, viz. Article, Substantive or Noun, Adjective, Numeral, Pronoun, Verb, Adverb, Preposition, Conjunction, and Interjection."

"322. The parts of speech which are neither declined nor conjugated, are called by the general name of particles. 323. They are adverbs, prepositions, conjunctions, and interjections."

"One group of substantives, the gerunds (scolding), belongs to a form-class with infinitives and with other verb-forms, in serving as head for certain types of modifiers, such as a goal (scolding the boys). For this reason a system of parts of speech in a language like English cannot be set up in any fully satisfactory way: our list of parts of speech will depend upon which functions we take to be the most important."
