(adj.)  /ˈluːkjʊl(ə)nt/

This is a great, but underutilized, word which describes something that is clearly expressed, often in reference to writing or speech. The secondary meaning was once the more prevalent one -that of something brightly shining or illuminated- but it has since given way to the rather more poetic figurative sense. It also has an adverbial form; luculently. May it help you luculently convey your thoughts.

Examples of use;
The author’s style demonstrates a luculent understanding of people’s lives.
The musical score was frequently discordant, but contained moments of luculent beauty.
Her luculent argument was complemented by her natural charisma.

The complex nature of the subject makes it almost impossible to speak of it luculently.
It is luculently apparent that this course of action is the correct one.

Etymology: Late Middle English. From Latin luculentus, from lux, luc- ‘light’.
