Background
Origin
FineType's registry describes a single word as one without spaces, made of letters and digits or joined by common separators such as a hyphen.[1] FineType's definition allows hyphens and underscores only in the middle of the value, so the first and last characters must be letters or digits.[1] FineType's registry notes that the type was called text.word before its v1 migration.[1]
Use
Most programming languages do not allow spaces in names, so a delimiter is needed to mark where each word starts and ends.[2] Some early languages, notably FORTRAN (1955) and ALGOL (1958), allowed spaces within identifiers.[2] Snake case replaces each space with an underscore and writes words in all lower case.[3] The hyphen is commonly used as a word separator when writing COBOL, Forth and Lisp.[2] Hyphen-separated names are also common in Unix for commands and packages, and are used in CSS.[2] C and Pascal-family languages avoided hyphens in names because the hyphen was their subtraction operator.[2]
A value with a space in the middle is not a single word, so a column that mostly fits but has a few spaced values may be free text or a list of names instead. (Meridian's view)
