偷偷破坏英语单词怎么说

"Stealthily sabotage Engpsh words" is a somewhat awkward and verbose way to express this idea. A more natural and concise way to say it might be "sneakily mess with Engpsh words," or simply "sabotage Engpsh words secretly." It's worth noting that this phrase might not be fully understood by all Engpsh speakers, as it is somewhat informal and could be interpreted in different ways. It might be helpful to provide more context or explain what you mean more exppcitly.
