About ことに

When 事(こと) 'thing' is combined with the case-marking particle に following a statement, it highlights that something is of a 'great extent'. Common translations include 'particularly', 'especially', or 'to my (A)'. This grammar pattern almost always describes some kind of feeling or emotion.

ことに is regularly seen after verbs, い or な-Adjectives.

In most situations, '(A) ことに (B)' can be translated quite literally as 'to a particularly (A) extent, (B)'.

Fun Fact

A very common expression 幸(さいわ)いなことに uses this particular grammar structure as a set phrase, and is often translated simply as 'fortunately', or 'luckily'.

幸(さいわ)いなことに、近所(きんじょ)の人(ひと)が私(わたし)の猫(ねこ)を見(み)つけて家(いえ)まで届(とど)けてくれた。

Fortunately, my neighbor found our cat for us, and brought her home.

Fun Fact

ことに may sometimes be seen before descriptions rather than following them. In these cases, it comes from the kanji 殊(こと), and is being used adverbially in the same was as 特(とく)に to mean 'particularly' or 'especially'.

Quick question – I’m under the impression that inverting the sentence order for some of these would come off more natural.

Example:
嬉しい殊に、みんなが協力してくれるようになりました.
vs.
みんなが協力してくれるようになりましたので、嬉しい殊に.

Maybe it would need a bit more tooling for it to be grammatically sound, but that’s just my two cents.

Hi, the Bunpro entry suggests that this ことに comes from the adverb 殊, but I cannot find any other sources that support that claim. It seems to just be regular こと. Also in the 幸いなことに entry it does say that this is the こと that means “thing”.

A bit confused about this lesson

Isn’t the “extremely” translation overexagerated ?
All my other sources refer to an emphasis of the emotion/feeling but I have yet to find an example mentioning an extreme quality in their translation outside of the case of a strong adjective which adds the emphasis by itself

for example in English if I said “as I was devastated” “as” has no role in the extreme emotion, I get the feeling ことに kind of works the same ? or am I mistaken ?
