Usage notes

• Though described as literary as of the 20th century, particularly since the 21st century colloquial usage also occurs, where it may be used humorously or as slang, "spicing up" the speech; compare also the Ukrainian бо (bo). Regardless of these trends, Russian ибо (ibo) typically remains being prescribed as literary only.
• The word's usage is increasingly frequent on the Internet due to its briefness compared to потому что (potomu što), although remaining rare in spoken speech.
