Adverbs : -ly ending

Hello,dear learners!
Today we'll study adverbs again. (Part 1 is here.) Hope, you  will find some useful tips in this post.

The most common way to form adverbs is to add -ly to adjectives:
gentle-gently, wonderful - wonderfully, sad - sadly, etc.

But there are some words with  ending  -ly   which are not adverbs. They are adjectives :
elderly,cowardly,friendly,likely,deadly,lively,lonely,silly,ugly,lovely, etc.
John is a kind and friendly person.
It was an ugly creature.
One should use the words way/manner to form their adverbs:
They talked in a friendly way/manner.



The adverbs loud(ly), chear(ly), quick(ly), tight(ly), fair(ly), slow(ly) are often used without  -ly in everyday English.
 The girls are laughing loud(ly).

Some words have the same form for both adjectives and adverbs. They are:
hard,fast,free,high,low,deep,early,late,long,near,straight,right,wrong,and also hourly,daily,weekly,monthly,yearly.
This is my favourite monthly magazine. (adj.)
This newspaper comes out daily.(adv.)

Some adverbs have two forms, each with different meaning:
deep - a long way down;
deeply - very.
He is a miner and works deep under the ground.
Her words touched him deeply.
free- without a payments
freely - without limit
We can use the Internet  here for free.
 I can talk freely here, in the circle of my friends. 

Other examples:

high- at/to a high level (high in the sky)
highly - very much ( highly qualified)

late - not early (She is always late. )
lately - recently (She is so busy lately. )

near - close (There was nobody near here.)
nearly - almost (It was so funny - we nearly died laughing.)

hard - with effort (He worked hard)
hardly  - almost not (I can hardly hear you.)
