\Anti-' means 'against'. The opposite is 'pro'. 

Anti-fascist     =/=     pro-fascist

 

Another

Typical mistakes: 

We need an other chair. 

I've got other three days holiday. 

1. 'Another' is written as one word. 

We need another chair. 

2. Normally, 'another' is followed by a singular noun: we can say 'another day', but not 'another days'. However, 'another' can be followed by 'few' or a number with a plural noun. 

I've got another three days holiday. 

There's room for another few people in the back of the bus. 

Note that instead of 'another three days, we could say 'three more days', but not (in this sense)'three other days'. 

AND instead of infinitive with Try, Wait, Go, Come...

1. In informal English, we often used 'try and' instead of 'try to'. 

Try and get some unsalted butter (Try to... is also possible). 

I really must try and see Paul this week (Or: ...try to...). 

This structure is possible with the simple form 'try', but not with tries, tried or trying. You cannot say 'I tried and got...' or 'He always tries and get...'

'Wait' and 'See' is similar. 

Let's wait and see (Not: 'We waited and saw' or 'Let's wait to see'). 

2. After 'come', 'go', 'run', 'hurry', 'stay', 'stop' and some other verbs, 'and' can be used instead of an infinitive of purpose. 

Come and have a drink. 

Hurry up and get dressed. 

Say and have dinner. 

We ought to stop and think. 

Would you go and tell the children to shut up? 

In these cases, however; third person forms and past tenses are possible. 

He usually stays and has dinner with us after the game. 

I went and had a drink with John yesterday. 

The 'to' infinitive is unusual in expressions like these and cannot be used after 'hurry up'. 

Informal American, 'and' is often left out after 'go'. 

Go jump in the river. 

AND

'And' is used to connect expressions that are grammatically similar, for example: 

Nouns: bread and butter

Verbs: They and danced all night. 

Clauses: I went home, and Mary stayed at the station. 

When there are more than two expressions, we usually put 'and' only before the last one. 

Bread, butter and cheese

They drank, sang and danced all night. 

I went home, Linsay went with me, and Mary stayed at the station. 

When expressions are joined by 'and', we often put the shortest first. 

big and ugly    cup and saucer

Some common expressions with 'and' come in a fixed order which cannot be changed. 

hands and knees (Not: knees and hands)    Knife and fork 

bread and butter    men, women and children    fish and chips 

When adjectives are used before a noun, they are sometimes joined by 'and' and sometimes not, depending on the type of adjective. For instance, we say 'a big black insect', but 'a black and yellow insect'. 

When two expressions are joined by 'and', words which come in both expressions (e.g. articles) can often be left out in the second expression. For instance, the bread and (the) butter, in UK and (in) USA. 

 

Among Vs Between

1. Compare the following: 

        a. S/he was sitting between Bunna and Vitou. 

            I saw something lying between the wheels of the train.

            Cambodia lies between Thailand, Vietnam and Lao. 

        b. We found a little house hidden among the trees. 

            S/he was standing laughing among a crowd of journalists. 

    We say that something is 'between' two or more objects, people, countries and so on when we see the surrounding objects and so on separately, there are not very many of them, and each one is clearly distinct from the others. 

    We say that something is 'among' a mass, a crowd, or a group: a collection of things when we do not see separately. 

    We prefer 'between' when we want to say that there are things, or groups of things, on two sides: 

        A little valley between high mountains. 

2. Words like 'divide' and 'share' are followed by 'between' when we use several singular nouns. 

        He shared his property between his wife, his daughter and his sister. 

        I divide my time between teaching, writing and lecturing. 

    With plural nouns, 'between' and 'among' are both possible. 

        S/he divided his money between/among his five sons. 

    We always talk about the difference 'between' things. 

        What's the difference between a crow and a rook? 

3. 'Among' can be used to mean 'one of', 'some of' or ' included in'. 

        Among the first to arrive was the Fantasian ambassador. 

        S/he has a number of criminals among his friends. 

Always

Typical mistakes: 

Always I ask myself what I am doing here. 

Never I find the answers. 

'Always' does not normally at the beginning of a sentence.' It's usually put with the verb, in same position as other frequency adverb. 'Never' goes in the same place. 

I always ask myself what I'm doing here. I never find the answer. 

But note that 'always' can be put at the beginning of imperative sentences. 

Always put on your safety belt when you drive. 

When 'always' mean 'all through the past until now', it is usually used with a present perfect tense. 

I've always believed he was innocent. 

You've always been my closest friend. 

Although Vs Though

Very often, both of these words can be used in the same way. 

They're a nice family, (al)though I don't like young Sander much. 

There one or two differences: 

1. 'Though' is more common in informal speech or writing. 'Although' can be used in all styles. Compare the following: 

Although the murder of the Archduke was the immediate cause of the First World War, the real reasons for the conflict were very much more complicated. 

I'd quite like to go out, (al)though it is a bit late. 

2. 'Though' is often used with 'even' to give emphasis. 'Even although' is not possible. 

Even though I didn't understand a word, I kept smiling. 

3. 'Though' (but not 'although') can be put at the end of a sentence, with the meaning of 'however'. 

It was a quiet party. I had a good time, though. 

In longer sentences, 'though' can also come in other position: 

The strongest argument, though, is Britain's economic and political dependence on the United States. 

In cases like these, 'though' is an adverb. 'Although' can only be used as a conjunction.
