dent corn
LowSpecialized / Technical / Agricultural
Definition
Meaning
A major type of field corn (Zea mays indentata) with kernels that have a distinctive depression or 'dent' at their crown when mature, primarily grown for livestock feed and industrial uses.
A starchy, non-sweet variety of maize that serves as a commodity grain for animal feed, processed food ingredients (e.g., cornmeal, corn syrup), ethanol, and other industrial products. Its name derives from the physical indentation on dried kernels, resulting from the hard endosperm shrinking away from the soft starchy core.
Linguistics
Semantic Notes
The term is part of a technical classification of corn types (others include flint corn, flour corn, sweet corn, popcorn). It is a count noun ('a field of dent corn'), but often used in non-count contexts to refer to the commodity grain ('processed dent corn'). It is not a variety name but a category.
Dialectal Variation
British vs American Usage
Differences
The term is used identically in technical agricultural contexts. In everyday UK English, 'maize' is the more common term for the crop, while 'corn' often refers generically to grain (especially wheat). In American English, 'corn' defaults to maize, making 'dent corn' a recognized subtype.
Connotations
Neutral, technical descriptor. In the US, it connotes large-scale Midwestern agriculture and commodity markets.
Frequency
Very low frequency in general language; appears almost exclusively in agricultural, economic, or botanical texts. Slightly more common in American English due to the prominence of corn cultivation.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'corn' as 'зерно' (grain in general). 'Dent corn' is a specific type of 'кукуруза'.
- The 'dent' refers to the physical shape, not to damage or a 'вмятина' from impact; it's a natural characteristic.
Common Mistakes
- Using 'dent corn' to refer to sweet corn eaten on the cob.
- Treating it as a plural countable noun incorrectly (e.g., 'dents corn'). It is 'dent corn' (compound noun) or 'kernels of dent corn'.
- Confusing it with 'flint corn' or 'flour corn', which have different kernel structures.

FAQ
Frequently Asked Questions
No, dent corn is very starchy and not sweet. It is harvested when fully mature and dry, and is processed into meal, syrup, or used as animal feed, not eaten fresh off the cob.
Not all, but the vast majority of field corn grown in the United States is of the dent corn type. Other types like flint corn or flour corn are also field corn but are less common commercially.
The dent forms because the hard outer endosperm contracts away from the soft, starchy center of the kernel as it dries, creating the characteristic indentation.
It is a standard botanical/agricultural classification based on kernel morphology, not a brand name. Its scientific classification is Zea mays indentata.
