What nuance does かかる adds to て-form of a verb?


I sometimes come across verbs ending with「てかかる」, for example 食ってかかる and
舐めてかかる. It sometimes show up in novels I'm reading, for example

> 若い私はその時暗に相手も私と同じような感じを持っていはしまいかと疑った。そうして腹の中で先生の返事を **予期してかかった** 。(こころ-上-三話)

> でも、丸が目撃証言だけで信じるなんて珍しいね。噂話には **疑ってかかる** ほうなのに。

Does adding かかる after a て-form verb emphasize the verb's meaning? Also, I
wonder how てかかる is related to 連用形+かける.

I already read [this
question](https://japanese.stackexchange.com/q/42544/41067) and its related
links but I can't find anything helpful.




[かかる](https://dictionary.goo.ne.jp/word/%E6%8E%9B%E3%82%8B/) has quite a few
meanings.

かかる in 食ってかかる is used in the sense of _to attack_.

The others are used in the following sense:

> 26
> 多く、動詞の連用形に接続助詞「て」を添えた形に付いて、初めからそのような状態で、またはそのように思い込んで、事に対する意を表す。「相手をのんで―・る」「だめだと決めて―・る」

I think a modern relevant word is とりかかる = _to start working on_.

As these suggest, the basic nuance is "prejudice, preconception" in the
attitude of dealing with things: 舐めてかかる = face them with underestimation;
予期してかかる = expect a certain answer (beforehand/before getting an actual reply);
疑ってかかる = treat with doubt (from the start).
