### A Certain / A Particular

- If, on a certain day, Q and T enter the building second and third …
- If the fewest possible colors are used and one of the countries is the only one of a certain color …

It seems that “a certain” means “some” which takes widest scope. I.e. in that last example:

- There is some color such that one of the countries is the only one of that color
- and not: one of the countries is the only one such that there is some color that it is of.
- (This second sentence is always false, because for each country, there is some color that it is of).

### Any

There are various ways in which this can be used, and a complex interaction with other operators (negation, modals).

Some Examples from logic puzzles.

### Floating Each

Normal:

- Each of six scientists A, B, C, D, E, and F are to present a paper at a one-day conference.

Floating:

- Six scientists A, B, C, D, E, and F are to present a paper each at a one-day conference.
- Exactly six of seven jugglers — G, H, K, L, N, P, and Q — are each assigned to exactly one of three positions

### Except

- No two plays by the same playwright will be scheduled for any of the five weeks, except for week 3, for which two plays by playwright R will be scheduled.

### Only, Alone

### Respectively

- F and E are the fifth and sixth presenters respectively.
- => F is the fifth presenter.
- => E is the sixth presenter.
