The difference between 路 and 道? I feel that a very important difference could possibly be highlighted here.  I am not entirely sure.  

For one, I do see the difference between the two with a grand scale.
With that said, I also under stand the importance of 路, especially when with the word 露. Hailing from a City of Rain, I had the question come to light.

Does this word have a con notation strictly on the MDBG site?
It also includes the definition of betray, is that then in the eye of the be holder?

路  would seem to stem from foot, mouth and each/every .  Then does an implication exist that could be misused?

Is 路 then a step on the way to 道 through proper motions?

Edit:  The reason I came across this was because I was re minded of a girl with whom I played League with at a time. haha.  That was coupled with the fact that 露露 is also an almond milk, which I wrote along the line of yesterday. 

The original question stemmed from the line following:  "锏是一种中国传统古代兵器之一。"  Intrigued with the usage of 之一，　I had wanted to build a sentence using both the Chinese almond milk, and this one.
Your usage of character formation may not be always correct. E.g., 露 used to have that meaning (well before the 12th century AD), but now it means &quot;water drops (on/from plants)&quot;.
In general, 道 is a bit more abstract than 路, silimar to &quot;path&quot; and &quot;road&quot; in English. 路 often means the road you're going on, and 道 can have the meaning of &quot;method/approach&quot;.

– 你从哪条路过来的？ Which road did you come from?
– 我从那条小道过来的。 I came from that small path.

Usually they are interchangeable, but sometimes...

条条大路通罗马。 (not 大道)
All roads lead to Rome. (not &quot;path&quot;)
(road name) XX大道 (Blah Boulevard)
XX大路？ (Blah Big Road)

道 can also mean a social subject,

混白道，混黑道 (do business and run gangs)
白路/黑路 (white road and black road)
