What does divide mean?
To divide is to separate something into distinct parts, whether physically cutting an object, apportioning shares of a resource, or splitting a group into smaller units. The word also carries a strong figurative force: to divide people is to create discord, so it often appears in discussions of politics, religion, and society. In mathematics, dividing is the arithmetic operation inverse to multiplication. As a noun, a divide names a clear boundary or gulf — most famously the Continental Divide of North America, a ridge that determines which way rivers flow, and more abstractly gaps such as the digital divide between those with and without internet access. Derived from the Latin dividere, meaning to force apart or distribute, the word entered English via Old French and remains one of the most versatile verbs in the language. Its connotations range from neutral (dividing a cake) to charged (a divided nation), making context essential to interpretation.
To separate into parts, sections, or groups; to allocate among several people; to cause disagreement; or, in mathematics, to carry out division.
"They agreed to divide the profits equally among the partners."
Often used with 'into' (divide into parts) when describing separation, and with 'among' or 'between' when describing allocation.
A boundary or point of separation, especially a ridge of high ground separating river drainage basins, or a marked difference or gap between two groups or things.
"Closing the digital divide has become a priority for policymakers."
The geographical sense is capitalized in fixed terms such as 'the Continental Divide.'
As a noun, the plural refers to multiple boundaries, ridges, or gaps between things.
"The region's divides channel water either east toward the Atlantic or west toward the Pacific."
The same Latin root that gives us divide also gave us widow — literally 'the one left divided from her husband.'

Etymology of divide
Divide comes from the Latin dividere, meaning to force apart, separate, or distribute, formed from the prefix dis- ('apart') and the root related to vidua, meaning 'widow' — literally someone divided or parted from their spouse. The word passed into Old French as diviser before entering Middle English around the late fourteenth century. Cognates sharing the same Latin root include dividend, individual, and devise.
