Related to Wordnet

I want to find all words that occur commonly with a given word. For example the words light, sunshine, breakfast, alarm commonly occur with the word "morning".
Where can I find such information?
I hope this question is relevant on this site.

A:

"all words that occur commonly with a given word" – it's called "collocation."  
Look up the collocations of the word you have in mind. E.g., morning in the Online OXFORD Collocation Dictionary. 
adjectives:   

this, tomorrow, yesterday | Friday, Saturday, etc. | early, late The side of the mountain appeared pink in the early morning light. | April, May, etc. | spring, summer, etc. | beautiful, bright, fine, sunny | cold, frosty, grey

You can use a concordancer. Here's a link to a concordancer.
It basically searches various language corpuses, and pulls out strings of text with the given word in. You can sort by the word to the left, or to the right. You can also choose to sort be two/three/four etc words to the left or right as well. And you can set the length of the readout from 10-1000 lines. 
Different concordances will be able to search in more or less detail (i.e. pull out X + adjective, or X + noun combinations). Many will also give you the frequency of the different collocations in descending numerical order. Here is a sample from a readout for  "water [word]". It's relatively short but long enough to give you an idea:

Here we can see that the word shortage/s seems to have some special relationship with the word water. At the bottom (I've deliberately cut it off because it's too long) there are twenty-seven instances of ski or skiing and so forth. This shows a very strong relationship.
At the bottom of the readout from the concordancer that I've linked to, they also give the frequency  of each item within that selection. You need to weed out the accidental stuff, and grammatical words. Here's the reading for water [word]:

and=383 in=139 the=87 to=79 gypsy=76 is=68 on=63 it=59 s=59 was=59 from=54 i=49 you=48 that=46 for=42 but=41 yeah=37 he=36 a=33 or=32 so=32 they=31 as=28 at=28 with=28 heater=27 supply=26 oh=24 she=23 then=23 of=22 out=22 when=21 which=21 if=20 all=19 pump=19 into=18 bottle=16 over=15 there=15 this=14 now=13 skiing=13 well=13 by=12 we=12 had=11 right=11 uh=11 water=11 what=11 where=11 will=11 would=11 comes=10 down=10 rafting=10 tank=10 are=9 before=9 fishing=9 like=9 no=9 off=9 only=9 up=9 aerobics=8 bill=8 colours=8 cress=8 too=8 um=8 until=8 why=8 without=8 yes=8 because=7 below=7 can=7 does=7 gets=7 line=7 look=7 sports=7 around=6 cooler=6 do=6 just=6 landing=6 mm=6 near=6 not=6 one=6 pipe=6 please=6 pollution=6 seal=6 ski=6 some=6 system=6 were=6 after=5 ah=5 between=5 coming=5 dripped=5 even=5 every=5 fish=5 has=5 here=5 his=5 leak=5 okay=5 rat=5 round=5 running=5 rushed=5 snake=5 softener=5 supplies=5 again=4 an=4 barrels=4 base=4 boils=4 bottles=4 colour=4 could=4 did=4 er=4 goes=4 heaters=4 level=4 lilies=4 looked=4 standing=4 them=4 till=4 your=4 almost=3 also=3 baby=3 bath=3 bed=3 boiled=3 came=3 chestnuts=3 color=3 come=3 contained=3 cos=3 doesn=3 dripping=3 fell=3 fountain=3 freezing=3 give=3 go=3 going=3 have=3 hot=3 ice=3 its=3 jack=3 jug=3 last=3 left=3 loss=3 mark=3 molecule=3 my=3 next=3 pipes=3 polo=3 projects=3 ran=3 rates=3 really=3 see=3 shortage=3 slowly=3 soluble=3 something=3 stops=3 systems=3 take=3 taken=3 than=3 though=3 through=3 torture=3 towards=3 two=3 under=3 while=3 within=3 

You also need to be aware of which corpus you choose to select from. This one seems to have included a book about water gypsies so this  collocation returns a freak number of water gypsies. But from the above list we can pull the following collocations:

heater=27 supply=26 pump=19  bottle=16  skiing=13 well=13 water=11 rafting=10 tank=10 fishing=9  aerobics=8 bill=8 colours=8 cress=8 sports=7 cooler=6  landing=6  pipe=6 please=6 pollution=6 seal=6 ski=6 system=6 coming=5 dripped=5 leak=5 rat=5 round=5 running=5 rushed=5 snake=5 softener=5 supplies=5  barrels=4 base=4 boils=4 bottles=4 colour=4 heaters=4 level=4 lilies=4 looked=4 standing=4 baby=3 bath=3 bed=3 boiled=3 came=3 chestnuts=3 color=3 dripping=3 fell=3 fountain=3 freezing=3 hot=3 ice=3 jack=3 jug=3 last=3 mark=3 molecule=3 pipes=3 polo=3 projects=3 ran=3 rates=3 shortage=3 slowly=3 soluble=3 something=3 stops=3 systems=3 torture=3 

If your search includes word families then the results for colour, colours and color would appear together, so you'd see that it would actually be fourth on that list. I find it helps to sort these kinds of results alphabetically. 
The linked-to concordancer won't search by part of speech. However, many do, and the Original Poster would need to do a more specific search for morning using parts of speech. This is because morning most frequently occurs as the last word in a sentence. The words following the word morning are likely to have no special relationship with it whatsoever!
Hope this is helpful.
