Mistake In Birthday Wish

Seniors please tell me,
What is wrong in sentence if I write' We all wishes you Happy Birthday "
instead "we all wish you happy birthday".
How big mistake it is grammatically ?
Please help me to come out of this confusion...........
Thanks

Dear User,
As the layman always said "keep it simple"....Most of the companies keep the Birthday cards with simple message "Happy Birthday" with the company logo and signed off by the group HR head.
The sentence mentioned by you is gramatically incorrect

Thanks Pon ,
You made my day by saying "Both the sentences are acceptable. "
I was very conscious since yesterday.......................................
Thanks a lot........

Dont leave the Focus, the objective behind sending these lines was to wish somebody, and not to show that you fully understand the grammar.

Sure Prateek , I know it was a mistake n I need to work on that but I expressed my happiness to Pon bcoz the quote was circulated in office and if it is correct I may not feel embarrassed which I am since ystrday.

Hi ravitashukla1 ,
"We all wishes you Happy Birthday" - sends across a message , as if you are just conveying it(the birthday wish).
whereas
""we all wish you happy birthday" - sends across the same message however it includes the conveyor (i.e in this scene you) too in the group of other people who are wishing.
Thanks & Regards,
Rahul

Hi,
I think the fact that you sent out the Birthday wishes should be the focus here, English grammar is not always easy...and I am English :-)

We all "wishes" is as correct as the "Why Kolabori the" language is correct as Tanglish and as Malayesians" write as they speek (skool for school, Teksi for Taxi, Bas for Bus, Vhay for danger Dhobi for Laundry etc).
It is as correct as, if we write "We all likes or we all goes to-- If you do not cosider basic grammar everything may be correct.
I did not know the meaning of BTW my children (now all top executives in India and in USA) were mailing me for some days recently over a "Circuit Mail" with 12 members in our family. BTW stands for "by the way" I learnt from my younger daughter,an Associate Professor in IIT-Madras.
Circuit Mail is for 12 members witten from 4 stations ( USA, Chennai, Visakhapatnam and Bhubaneswar) everyday which is read by everybody. One mail provides all important matters of everybody for everybody.
So we encourage creativity and innovation in communication in such usages.
With regards and best wishes to everybody.

It is mistake in plural form of wish.
it is same like.
1) "Fish" is correct form and "Fishes" is incorrect.
2) "Hair" is correct form and "Hairs" is incorrect.
It is like:-
1) Main "Hindustani" hun - singular form
2) Hum sab "Hindustani" hain - Plural form
3)मुझे "ठण्ड" लग रही है | - Singular
4)हमें ठण्ड लग रही है | - Plural
I think it is sufficient to understand.

Dear friends ,
Grammar is life of any language,
a fact not to be missed.Best wishes.
