Negating participles and gerunds

Question

I am trying to ask how to negate participles and gerunds and will use examples that may or may not be idiomatic, as follows:

(a) pouvant de patience

(b) en pouvant

(c) en pouvant de patience

(d) en en pouvant

Example (a) is supposed to be a participial modifier meaning "capable of patience."

In (b), also a participial phrase, de patience has become en.

Example (c) is a gerund resulting from concatenating the preposition en and (a).

Example (d) is a gerund resulting from concatenating the preposition en and (b).

Again the examples may be unidiomatic or even ungrammatical (if so please let me know), but I hope it is clear what kind of examples I am trying to generate.

Question

How one should place ne plus in each of these?

For instance, (d) would give rise to these possibilities.

n'en en pouvant plus
en n'en pouvant plus
en en ne pouvant plus

Background

As to being idiomatic, I am particularly doubtful of (d). en en may have a problem that en la or en y doesn't.

This other question of mine is somewhat related. Thanks.

Answer 1

First of all, capable of patience != pouvant de patience which means nothing. In french, you'll find posséder de la patience or avoir de la patience or être patient or prendre patience or faire preuve de sang froid. I think the last one is the best for your meaning of capable of patience.

These don't exist : n'en en pouvant plus; en en ne pouvant plus. The one is gramatically correct, but never used. en n'en pouvant plus

In general gerund is unused in french. To place negation in your sentences, you'll have to place it on the previous verb. I couldn't find a way to use gerund on faire preuve de sang froid. Example : The surgeon is operating with composure. = Le chirurgien opère en faisant preuve de sang froid. To add negative : The surgeon isn't operating with composure. = Le chirurgien n'opère pas en faisant preuve de sang froid. To add negative with "plus" : The surgeon isn't operating with composure since his accident. = Le chirurgien n'opère plus en faisant preuve de sang froid depuis son accident.

For your information, "plus" is used for something what had been positive.
