Is it grammatical to have と同じぐらい after a verb? I would have expected to see a
nominaliser (の) inserted. Presumably this is the usual と that comes with 同じ,
which marks the thing to be compared against, rather than either of the と
which I would expect to see with a verb (quote/conditional).

question
grammar particle-と comparative-constructions
Is verb + と同じくらい grammatical
Grammatically correct or not, searching on
[shonagon](https://clrd.ninjal.ac.jp/bccwj/) gives a few result without の.
Searching with の gives about x2 results, so you can be assured that verb + の +
と同じくらい is more common. In the below samples, の can always be inserted.

* * *

There may be several explanations though I'm not sure if any of them is valid.
The absence of の is a kind of things native speakers would just pass without
much thinking.

  1. It is an error by confusion with other constructions. For example, there's も同然 which I think comes more often without の.

  * 犯罪を犯したも同然 - の can be inserted, but less frequently.

  2. の is just omitted from のと同じくらい

  3. と plays the double role of nominalizer and comparison particle. Technically it should be とと, which is of course impossible and contracted.
