Learn English – ‘impressionable’ vs. ‘suggestible’

The two terms are closely related, and even interchangeable in many cases. However, the two words focus on different things. Alliance is more about mutual interests or benefit, while coalition is more about doing some action.

The use of both terms is not limited to the political context. They can be used in other contexts: military, financial, commercial, technological, and so on. Having said that, I agree that coalition is used most often in the political context for "a temporary alliance of political parties forming a government or of states" (see below).

Here are their definitions, according to Oxford dictionary:

alliance (noun)
1. A union or association formed for mutual benefit, especially between countries or organizations.
1.1 A relationship based on similarity of interests, nature, or qualities.
1.2 A state of being joined or associated.

coalition (noun) A temporary alliance for combined action, especially of political parties forming a government.

Here is a quote from Get Them On Your Side by Samuel B. Bacharach (chapter 5):

Formally defined, a coalition is a politically mobilized collection of interest groups or individuals committed to achieving a common outcome (i.e., resistance or change). Through political mobilization you create a group that has some sense of shared goals and/or a sense of connected interests. A coalition is an alliance for joint action.

In short, a coalition is an alliance for joint action.

First, let's talk about their interchangeability. There are some contexts where the two words could be used to mean "additional"; however, I think there seems to be a subtle difference in meaning when the word further is used:

The summit ended without any more talks.
The summit ended without any further talks.

I could not have run any further.
I could not have run any more.

In the case of the summit meeting, the word further hints that talks might have helped two sides come closer to an agreement. That's because one meaning of further is:

further (adv.) at or to a more advanced, successful, or desirable stage
_{(from NOAD)}

In the case of the tired runner, any further suggests a greater distance, while any more suggests a longer time. While those meanings overlap, I think further might be a better word for a runner dropping out of a marathon, while more might be a better word for someone working out on a treadmill. That's because further also means:

further (adv.) by a greater distance, or for a longer way
_{(from NOAD)}

As for the book, I think the best way to describe the latest edition of a book is:

a new edition of the book

You might use another when comparing two different editions of the same book:

I bought a new copy of A Study in Scarlet.
Really? I thought you already owned that book.
I do, but this was another edition.

It's harder to use further, because, in the context of publishing, I would interpret further to mean:

further (adj.) additional to what already exists or has already taken place or been done
_{(from NOAD)}

However, I suppose we could:

The publisher has indicated a reluctance to print any further editions of this book.

In that last sentence, the adjectives new or more could work in place of further.
