Is: 'La letre con sangre dentre' a Spanish expression?

Question

I know it means: 'the letter with blood in it'. Although i thought it should be 'dentro'? (anyone...)

Someone told me about this and that you use it to describe when you want to say to someone how much you love or hate that person and you do this by really putting your soul and passion in to it.

What i would like to know if this is a genuine Spanish expression and if it's used alot?

I think Mariana's answer shows it as it is: A lesson with blood in it.. - annierats, Nov 14, 2011

Answer 1

I found:

La letra con sangre entra = Spare the rod and spoil the child

This is also the title of a painting by Goya.

Mariana, this impressive illustration convinces me you're right. - annierats, Nov 14, 2011

I thi8nk they will have very red letters imprinted on their bottoms.. - annierats, Nov 14, 2011

I agree with the other posts that "no pain, no gain" is a closer interpretation. This is not so much about discipline, but rather "learning methods". - Gekkosan, Nov 14, 2011

Answer 2

chileno said

No pain, no gain

I thought no pain no gain in Spanish was,

El que algo quiere, algo le cuesta.

Answer 3

No pain, no gain.

But I don't know if that what's the OP is looking for.

Maybe he or she should tell us what it means, besides of what translate to.

Hey Chileno, you meant for the last part to read, "besides what it translates as." - territurtle, Nov 14, 2011

yes, I was ina hurry... :/ - chileno, Nov 14, 2011

Answer 4

Eddy:

No pain no gain, it also means "al que quiere celeste, que le cueste"

Depends of who is saying it... the teacher or the student.

Right?
