geo-
C1
In the word ‘geology’, the prefix ‘geo-’ refers to the Earth.
A „geológia” szóban a „geo-” előtag a Földre utal.
Many scientific terms that start with ‘geo-’ are connected to the study of our planet.
Sok olyan tudományos kifejezés, amely „geo-” előtaggal kezdődik, bolygónk vizsgálatához kapcsolódik.
‘Geothermal’ uses the prefix ‘geo-’ to show that the heat comes from the Earth.
The prefix ‘geo-’ comes from a Greek word meaning ‘earth’.
Words like ‘geophysics’ and ‘geopolitics’ show how ‘geo-’ can be used beyond pure science.
Learner examples
In ‘geography’, the part ‘geo-’ means ‘Earth’.
Az angol „geography” szóban a „geo-” rész azt jelenti: „Föld”.
The word ‘geology’ has the prefix ‘geo-’, so it is about the Earth.
A „geológia” szóban szerepel a „geo-” előtag, ezért a Földdel foglalkozik.
When you see ‘geo-’ at the start of a word, think about land or the planet.
‘Geothermal’ heat is heat from the Earth; ‘geo-’ shows this.
Teachers sometimes explain that ‘geo-’ comes from Greek for ‘earth’.
Common mistake:
Learners may confuse ‘geo-’ with ‘global’ or ‘worldwide’. ‘Geo-’ specifically points to Earth, land, or physical aspects of the planet, not to social or economic ideas, unless those are explicitly tied to geography (as in ‘geopolitics’).
Meaning
prefix meaning “earth” or “ground”
Collocations
geology
|geography
|geothermal energy
|geophysics
|geopolitics
Synonyms
earth-related (A descriptive phrase rather than a morphological label; used in explanations, not as a bound prefix.)
Antonyms
astro- (A contrasting scientific prefix that refers to stars or outer space instead of Earth.)
Themes
science
