Etymology of dialogue and dialog

The word dialogue originates from Middle English “dialog” from Old French dialoge. As outlined by The Oxford Dictionary of World Histories, Old French “dialogue” stems from Latin dialogus through Greek dialogos (via dialegesthai) for ‘converse with’ or ‘speak alternately’ (Chantrell 248).  

The Greek word dialogos consists of dia ‘through’ + legein ‘speak,’ although philosophy students often associate Greek dialegesthai with Plato’s “practice of philosophical dialogue,” according to Cambridge University Press.

Should we use “dialogue” as a verb?

According to Bryan Garner’s GMEU, the verb dialogue is inferior to its noun counterparts. Garner even goes as far as to call the verb a “gratingly vogue” (or ‘annoyingly popular’) term that appeared near the 1960s.’ 

The American Heritage Dictionary (AHD) also supports Garner’s stance on the verb when it means “to engage in an exchange of views” (which is specific to North American English speakers). According to AHD, 80 percent of their 2009 Usage Panel rejected the verb, citing the verb’s “ugliness” and “awkwardness” within sentences. 

But if you’re unswayed from the verb, Garner warns that using dialoguing as a gerund is widely shunned (274). Instead, try sticking with “dialogued” (past participle) or “dialogue” (present tense).   

FAQ: Related to dialogue vs. dialog

What does “dialogue of the deaf” mean?

If someone describes a conversation as a “dialogue of the deaf,” it means either party of a conversation is unresponsive to what the other person says (“Dialogue” 479). English speakers began using this particularly odd expression in the 1970s’ as a translation of French ‘dialogue de sourds’ (Chantrell 248).  

What is a monologue?

A monologue (also spelled as “monolog”) is a noun that means ‘a long speech by one person’ that’s a part of a play, movie, or broadcast program. Additionally, we can define “monologue” as ‘a person’s annoyingly long-winded speech or lecture during a conversation.’ 

Along with contextual similarities, the noun monologue shares a similar origin with “dialogue.” According to Lexico, the word monologue entered the English language from 17th century French, where it originated with Greek monologues for ‘speaking alone.’ 

What does duologue mean?

The word “duologue” is generally a theatrical term that means ‘a conversation between two people only.’ According to GMEU, the term is commonly confused with dialog or dialogue because it’s akin to the term “monologue” (274). But unlike “monologue” or “dialogue,” we never spell “duologue” as “duolog.”
