Three curtailments

I.

I can separate two high places.

Remove one letter, and I can separate two high places.

II.

I can connect two high places.

Remove one letter, and I can connect two high places.

III.

I can separate two high places.

Remove one letter, and I can connect two high places.

Notes:

• All of the words are singular nouns.
• "High" is relative.

Hint #1 for III:

Both are covered by water.

Hint #2 for III:

I never said you had to remove the first letter.

1

[v]alley

2

[b]ridge

3

[b]lock , [t]rack ,

EDIT for 3 , with the new clue "removing any letter" , which I did not add earlier, assuming that the only first letter had to be removed.

f[j]ord or f[i]ord

• Wait... what? The third one changes two letters. Commented May 13, 2015 at 3:50
• @EliasBenevedes , no, only one letter changes, but I am giving two alternate solutions , with the last comma indicating more possibilities.

I.

I can separate two high places.

Remove one letter, and I can separate two high places.

valley -> alley (valley can separate mountains, alley is a street which separates rows of potentially high trees)

II.

I can connect two high places.

Remove one letter, and I can connect two high places.

bridge -> ridge (bridge can connect two trees, cliffs, whatever, a ridge is a connection of mountains in a way)

III.

I can separate two high places.

Remove one letter, and I can connect two high places.

I am not sure. Maybe swale -> wale? A swale is a bit like a valley and a wale seems to be something like a belt or strap that you could use to connect two high places.

• Thumbs up to the first two. Commented May 12, 2015 at 13:14

III.

Fjord and Ford. A fjord separates the high cliffs on either side. A ford joins the two sides of a river at a passable point. And both are covered with water.

For II, I think it's

It's BRIDGE and RIDGE

For III could it be

Privet separates houses, and Rivet connects the beams in skyscrapers

• Clever! Not what I had in mind, but does kind of work. Also, TIL what that word means. Commented May 12, 2015 at 14:49

Huh - for II I was thinking:

Bridge/Bride, since marriages between royals were often used to cement alliances. However, bridge/ridge does seem to make more sense :)

• that is lateral thinking. I like that one. Commented May 12, 2015 at 17:49
