Could you correct, please, this text? Thank you for your help...
Family stories usually show some honourable values, defile memories and enrich our respective life with their lessons giving in metaphor form . The next one happened to my father during his childhood, an event which modified his vision of life forever and ever.
Further to that account from my father, I was moved deeply and I promised him that I will sponge off every single day as a memento of my dead uncle, Yves.
Rather than simply rewrite your sentence I will give you the reasons behind the corrections first. I have them listed here in the order of how they should be corrected.
The word 'defile' means:
1. To make filthy or dirty; pollute: defile a river with sewage.
2. To debase the pureness or excellence of; corrupt: a country landscape that was defiled by urban sprawl.
3. To profane or sully (a reputation, for example).
I'm sure you actually wanted a word which means the opposite of this such as: 'honour'.
Since the word 'our' precedes the word 'life' we see that it is actually more than one life - it is the life of each person, which is plural, 'lives'.
The tenses of the verb 'to give' are:
Base Form: Give
Past Simple: Gave
Past Participle: Given
3rd Person Singular: Gives
Present Participle/Gerund: Giving
In your sentence you would use the past participle. "...their lessons given in metaphor form."
Although the word 'modified' does mean 'changed' - it is more likely you would find the word 'changed' in this sentence.
"Further to that account from my father, ..."
"Following my father's account, ..."
"I was moved deeply and I promised him that I will sponge off every single day as a memento..."
In this case it is more appropriate to say 'soak up'.
Also, the word 'memento' means - "a souvenir or reminder of the past events." You actually want the word 'memory' here.
"...I promised that I would soak up every single day in memory of my dead uncle."
I hope you were helped by these comments.
