Pronunciation: [mˈɔː slˈə͡ʊd] (IPA) 
The word "more slowed" may seem confusing when it comes to spelling, but it's not as complicated as it may look. The correct spelling should actually be "more slowly" with the pronunciation /mɔːr ˈsləʊli/. The word "slowly" is an adverb which means done, moving or happening at a low speed. Therefore, if you're looking to imply a decrease in speed, you should use "more slowly" instead of "more slowed".
"More slowed" is not a standard term found in dictionaries, as it combines the comparative adverb "more" with the past participle form of the verb "slow." However, by breaking down its components, one can infer its meaning.
The adverb "more" is used to compare two or more things, usually indicating an increase in quantity or degree in relation to a certain characteristic. "Slow," on the other hand, is an adjective that describes the absence of speed, meaning a reduced rate of movement or progress.
Combining these terms, "more slowed" suggests that the referenced object or action has experienced a greater reduction in speed compared to something else. In simpler words, it indicates a further decrease, decline, or deceleration in tempo, pace, or momentum. For instance, if two vehicles are slowing down, one might say that the first vehicle is slowing down and the second vehicle is "more slowed" to express that the second vehicle is decelerating at a greater rate.
It is important to note that while "more slowed" might not be a widely recognized phrase, its meaning can be deduced from the individual words it comprises.
The word "more slowed" does not have a specific etymology. It appears to be a combination of the adverb "more" and the verb "slowed". "More" implies a greater degree or extent of something, while "slowed" is the past participle form of the verb "slow", meaning to reduce in speed or pace. When combined, "more slowed" suggests a further decrease in speed or a greater degree of slowing compared to a previous state.
