This lesson focuses on an array of interrelated adverbs which translate to "especially/particularly." Although some words may already be very familiar to you, others will be crucial additions to your vocabulary in preparation for the higher levels of the JLPT.
The adverb 殊に derives from the adjectival noun 異なり meaning "to be different," which you'll recognize from the verb 異なる with the same meaning of "to be different." In fact, 異なる is the verbalized form of 異なり.
It should come as no surprise, then, that 殊に means that something "especially/particularly" different. It is used to mark a higher degree of some quality in comparison to other things. This word is rather literary and is not heard too often in the spoken language.
Astronomy is especially important to sailors.
There was one person from earlier who particularly drew my attention.
The road had become especially worse by what the avalanche left behind.
In older language, 殊に could also mean "moreover."
Moreover, (they) say that the Nishiyama and Higashiyama are in full bloom at this time.
From 『猿座頭』 by 虎清狂
The adverb 特に also means "especially/particularly" by indicating that something stands out as being different than the norm, but unlike 殊に it can also refer to "special/preferential" treatment.
Today is particularly hot.
Employment is particularly worsening in developing countries.
"Where there any problems?" "There weren't any in particular."
特別（に） can also be used as an adverb, indicating that the state or disposition of something surpasses other things. It also shares 特に's meaning of referring to "special/preferential" treatment. You will also see 特別 used as an adjectival noun to mean "special/particular." As an adjectival noun, it usually takes な, but it is also very common to find it in compound words.
8. 在留を特別に許可する。To especially allow for (someone) residing.
I don't need anything special.
There may be students who think that the Kanken is not particularly important to themselves.

格別（に）is also very similar to 特別（に）in that it marks an exceptionally true quality. It can also have the nuance of being "especially selected/treated with exception." The difference in nuance between it and 特別 is that it indicates that something is especially better.
Just like 特別, 格別 may also be used as an adjectival noun meaning "special/particular," and as an adjectival noun, it usually takes the particle の.
Winter is the season when hot pot tastes especially delicious.
With exception to rainy days, go to the gym daily.
I wish to express my deep gratitude for the substantial support you always provide.
格段に is particularly closely related to the word 格別（に）, but rather than indicating that something is far better than something else, its nuance indicates that the difference at hand is a "marked/noticeable" one at that. The difference is also usually a positive one. When it is used as an adjectival noun, it usually takes the particle の.
There is a substantial difference in skill between (him) and ordinary people.
If you ask me, I feel that (he) has markedly improved.
If you want to say that something is at a wildly different level than something, you can also use the synonym 段違いに. As an adjectival noun, it can take な or の.

Monsters wildly stronger than other monsters that appear in dungeons will appear.
Deriving from the te-form of the verb 取り分ける meaning "to distribute/divide,"とりわけ（て） means "especially," but it is preferred in objective contexts and is not used in relation to actions that are done purposefully or willfully.
This year has especially had a lot of rain.
Especially in the world of politics, it is safe to say that reformation will invariably fail.
Even if the whole world becomes yours, love thy home country above all.
Variation Note: とりわけて is identical in meaning and usage to とりわけ, but it is usually only encountered in writing.
とりわけ can best be understood as pinpointing what is "especially so among others." In this sense, it may be used to refer to personal opinion or the action of others, making it interchangeable with 特に, but it maintains its objective lens on the situation.
Among sports, I especially like soccer.
(Among other things, he) is especially patient about boxing.
Orthography Note: The Kanji spelling of とりわけ is 取り分け, but it is seldom used.
なかんずく, also more traditionally spelled as なかんづく, is a contraction of なかにつく and means "especially... among other things" and is a more literary, fancy synonym to the second usage of とりわけ.

From 『栃の実』by 泉鏡花.
Although all these adverbs can be used in negative sentences, the two synonyms that can only be used in negative structures are 別に and 別段. Both words mean "not particularly/especially," the latter form being more literary.
There wasn't anything particularly unusual there either.
He hasn't particularly written any incendiary passage abetting war.
Science isn't especially particular knowledge but ultimately knowledge itself and nothing more.
From 『科学編』 by 戸坂潤.
殊更 has two meanings, one of which is meaning "particularly" as the emphatic version of 殊更.
I will not particularly make issue of what exactly "good" and "evil" are now.
There is an extremely large amount of such funny stories in this compilation, but it isn't that (we) have particularly collected lots of them.
From 『中国笑話集』 by 駒田信二.
The second meaning of 殊更 is indicating "intentional/deliberate" action. In negative contexts, it may give off the meaning of "not particularly necessary to" which could be viewed the same as saying "no need to go out of one's way to."
In positive contexts such as Ex. 26, you can actually see how the "intentional" meaning derives from its use to "particularly" be a certain way but in a transitive context.
Particle Note: For this second usage, you may also see the particle に with no change in meaning or nuance.
His muscles especially swelled up (on purpose), emphasizing his manliness.
(I) wasn't singing that to intentionally have someone listen to it.
A far more common way to say "deliberately/on purpose," though, is わざと.

To think there'd be a woman who would purposely want to show off doing this sort of thing in front of people...
Orthography Note: The Kanji spelling of わざと is 態と, but it is seldom used.
In technical speech, the adverb 故意に will also be seen.
For instance, are you sure another person didn't use a comb on the person's head? Are you sure no one deliberately placed hair of an A-type individual there and then presented that to the court?
From 『死体は語る』by 上野正彦.
