Who had the time to find the 7 letters that actually formed 7 different words? Is this what they do at Berklee?
LOL. Well if we are prepared to stop and think then we can come up with various ideas about modes.
For example, we can take seven notes and depending in how and how many we use to arrange them have different sounds, chords of you will.
Modes are, as far as I'm concerned, are an after thought for any player, they are just an extra tool to have if you want them.
Never ever have I came across modes being notated or written down in any playing situation I have been in over the last 40 years.
But I have talked about them and used them as a device to add, as Malcolm says " colour" to a line I have played. I have used them as a collective name to explain the idea of what is involved rather than explain it note for note.
Again this would be a pro use for it if you knew them as did the person you were discussing it with.
In the same way I can read his ideas from a sheet without him showing me them, I can change those ideas as a collective by using certain modal ideas.
Most common use for me as Blues Player is in turnarounds.
Because I have a basic understanding of modes *( and that is all I have ever had ) I know that for example in a 1-1V- V Blues in C when I go to the 1V (F) I do not need to just play a transposed Ionian, the same when I go to the V.
No one ever writes such things, but I know I can do more than just move a box shape around whether it be a dom7 in three different positions, or a single modal idea in three different positions.
All this means is that in the 1-1V-V walking line,when the song moves from the V to the 1V you can stay on the V ( G) and walk down it though the 1V (F) without making the F the root of the 1V chord.
So it can be on the V of the song at the turnaround
G B D E F and using that F at the top rather than a root (the 7 of G7) walk back down
E D B to the C
Rather than being
G B D E F A G D to the C it can flow
G B D E F E D B to the C
Or rather than going to the V go to the ii and miss out that V to the 1V turnaround completely as a root orientated movement.
Again at the V of the song rather than going
G B D E F A G D to the C or
G B D E F E D B to the C
You can go to the ii (D) and play
D E F F# G F E D back to the C
So a simple Blues structure of 1-1V-V will have elements of modal harmony if you care to look.....or know where to look......if you want to.
p.s.
finding seven anagrams was easy.... one search under "seven letter anagrams" took seconds.....again it's about known what your doing rather than wasting time by not.
