Origine: Ndebele, Southern Africa
Source: Ndebele oral-tradition proverb; "Proverbs in Ndebele," northernndebele.blogspot.com (2019), which gives the gloss quoted here and adds that the line "can translate to something like the big elephant is killed by small ants". Earlier recorded here as documented on Wikiquote's "Ndebele proverbs"; that page, read directly, does not contain it.
La source l’explique: A lot of small steps can overcome a large problem.
