In this spelling based question, you must select the correctly spelled English word from the given options. Only one of the alternatives is spelled in accordance with standard English usage, while the others contain extra letters or incorrect sequences.

Introduction / Context:
This question examines your ability to recognise standard English spelling. Such questions are especially common in exams that test vocabulary and language accuracy. You are presented with four options where three words are misspelled variants of real English words, while one is correctly spelled. Your task is to identify the correct one, which requires familiarity with common English words and their usual letter patterns.

Given Data / Assumptions:

• The options are decanyter, ghoullish, accollade, and abruptly.
• Only one of these words is a correctly spelled standard English word.
• The other options resemble real words like decanter, ghoulish, and accolade, but their spellings are altered.
• No special context sentence is given, so you must rely on general knowledge of spelling.
• The answer must be the exact option printed, not a corrected version you imagine.

Concept / Approach:
To solve spelling questions, it helps to think of known words and check each option against them. abruptly is a common adverb derived from the adjective abrupt, meaning sudden or unexpected. Its spelling a b r u p t l y is standard. The other three words closely resemble real words but contain unnecessary letters or wrong arrangements. Decanter is a vessel for serving drinks, ghoulish describes something resembling a ghoul, and accolade is an expression of praise. The options decanyter, ghoullish, and accollade do not match these known spellings.

Step-by-Step Solution:
Step 1: Examine abruptly. This word is formed from abrupt plus the suffix ly. The root abrupt is spelled a b r u p t and adding ly gives abruptly, which is a familiar correct form. Step 2: Examine decanyter. It looks like a distorted version of decanter, which is spelled d e c a n t e r. The presence of y and the letter arrangement show that decanyter is incorrect. Step 3: Examine ghoullish. This resembles ghoulish, meaning frightening or cruel, which is correctly spelled g h o u l i s h with a single l before i s h. The double l in ghoullish makes it wrong. Step 4: Examine accollade. It is close to accolade, meaning award or praise, which is spelled a c c o l a d e. The double l after o in accollade is incorrect. Step 5: Since abruptly corresponds exactly to a known correct spelling, and all other options deviate from their correct forms, abruptly must be the right answer.

Verification / Alternative check:
If you consult a reliable dictionary, you will find abruptly listed as an adverb. The other forms decanyter, ghoullish, and accollade will not appear as standard entries. You might find decanter, ghoulish, and accolade instead. This confirms that abruptly is the only correctly spelled option among the four choices.

Why Other Options Are Wrong:
decanyter is an incorrect variation of decanter, with misplaced letters and an extra y.
ghoullish wrongly doubles the letter l and does not match the standard spelling ghoulish.
accollade wrongly doubles the letter l and differs from the correct word accolade.

Common Pitfalls:
Students sometimes choose misspelled words because they look more complicated and therefore seem more formal or correct. Another common problem is remembering only the approximate sound of a word and guessing the letters. Regular reading and paying attention to spellings in context, such as in textbooks or quality newspapers, can significantly improve your ability to spot incorrect forms quickly and accurately.

Final Answer:
The only correctly spelled word among the options is abruptly.
