Other forms: clarifications
Clarification is what you hope to achieve when you make an idea or concept less confusing and easier to understand. This often happens after a detailed or very clear explanation.
Loudspeaker announcements in bus terminals and train stations are always so muffled and difficult to understand that it would be nice if you could at least find someone afterward who could provide clarification. In the realm of science, clarification is also the act of removing solid particles from a liquid so that it is more pure and, in some cases, so that it is transparent.
