logía

Logía is a Spanish noun that refers to the suffix -logía used to name a field of study, science, or systematic inquiry. It derives from the Greek logos, meaning word, reason, or study, and entered the vocabulary through Latin and the long tradition of classical languages. The suffix -logía is productive in Spanish, linking a root to a domain of knowledge.

In practice, -logía attaches to a root to indicate the study of that subject. Common examples include biología (study of living organisms), geología (study of the Earth), psicología (study of the mind), sociología (study of society), meteorología (study of the atmosphere and weather), cosmología (study of the universe), and teología (study of divinity). The term epistemología (study of knowledge) also follows this pattern, as does ecología (study of the relationships between organisms and their environment). Some -logía terms denote theoretical or conceptual fields as well as empirical sciences.

Spelling and usage notes: logía carries an accent on the í in standard Spanish, signaling that the stress falls on that syllable. The suffix is a productive and widely used way to form names of disciplines, though not every emerging field adopts -logía; some prefer other endings or neologisms.

Related terms include alogía, a prefix indicating absence or lack of speech, which shares the same root but a different meaning. Overall, logía functions as a key linguistic device for naming systematic study in a broad range of domains.
