usage note for all

Expressions like all the farther and all the higher occur chiefly in informal speech: This is all the farther the bus goes. That's all the higher she can jump. Elsewhere as far as and as high as are generally used: This is as far as the bus goes. That's as high as she can jump.
Although some object to the inclusion of of in such phrases as all of the students and all of the contracts and prefer to omit it, the construction is entirely standard.

What does all- mean?

All- is a combining form used like a prefix meaning “other” or “different.” This form crops up occasionally in medical and scientific terms.

In chemistry, all- denotes the more stable of two geometric isomers. Isomers are molecules that contain the same numbers of the same kinds of atoms but in which the atoms have different structural arrangements.

All- comes from Greek állos, meaning “other.” This word’s distant cousins in Latin, alius and alter, which have similar definitions, give us words such as alien and alternative. The opposite of all- is the form aut-, from Greek autós, “self.”

What are variants of all-?

All- is a variant of allo-, which typically loses its -o- when combined with words or word elements beginning with vowels.

Examples of all-

One technical term that features the combining form all- is allonym, “the name of another person taken by an author as a pen name.”

The all- part of the word means “other,” but what about -onym? If you’re familiar with synonym and anonymous, you may be able to guess this combining form’s definition: “name.” Allonym literally translates to “other name.”

What are some words that use the combining form all-?

What are some other forms that all- may be commonly confused with?

Not every word that begins with all- is using the combining forming all- to denote “other.” Learn why allay means “to calm” at our entry for the word.

In some cases, all-, with the hyphen, is used to mean “whole” or “total,” as in all-American or all-out. This use of all- simply the combining form of the English adjective all and is therefore unrelated to the Greek-origin form all-.

Another easily confused combining form is al-, which is a variant of the combining form ad-, from Latin ad, “to” or “toward.” The -d- in this combining form often assimilates, or changes to match, the first letter of the combining form that follows; instead of adlure, for example, we say allure.

Break it down!

Esthesia is a medical term meaning “capacity for sensation or feeling; sensitivity.” With this in mind, the term allesthesia is a condition in which a person feels a sensation in a different part of the body from the point that was stimulated. Based on the meaning of all- and esthesia, what is a literal translation of allesthesia?
