The answer is ILLS, four letters. WOES occupies the same four squares at very nearly the same frequency, and when the clue is doing verb duty instead of naming a plural noun, the fill becomes AILS, IRKS or VEXES. Settle the grammar before you count, because that choice changes the entire candidate list.
One word doing two grammatical jobs
Troubles is a plural noun and a third person verb spelled identically, and a good clue will not tell you which one it means. Compare the two sentences: his troubles are behind him, and the noise troubles the neighbors. Same six letters, two completely different answer sets. This is the most common single reason a solver stalls on a clue this short.
There is a tell. Because the clue is just one word, the constructor has to rely on the answer matching in form, so the fill will always carry the same ending logic. A plural noun answer ends in the plural S of ILLS or WOES. A verb answer ends in the conjugated S of AILS or IRKS. Either way you are looking for a final S in the last square, which is worth knowing before you have a single crossing.
Ills almost never appears in the singular
An ill, as a noun meaning a misfortune, has effectively dropped out of everyday speech. What survives is the plural in fixed company: the ills of society, social ills, the ills that flesh is heir to. The singular hangs on only as an adverb or adjective, in speak ill of and in ill at ease. That imbalance is exactly why ILLS is a crossword staple and ILL on its own is clued differently, usually as sick or as unwell.
WOES behaves the same way. Nobody reports a single woe, but financial woes, injury woes and travel woes are all normal newspaper English. Sports pages and business pages run on the word, which is where most editors get the surface for it.
Every plausible fill, counted out
Match the square count, then check the part of speech against the column on the right.
| Letters | Answer | Reading |
|---|---|---|
| 4 | ILLS | Plural noun, the default |
| 4 | WOES | Plural noun, slightly more dramatic |
| 4 | AILS | Verb, what is troubling you |
| 4 | IRKS | Verb, annoyance rather than hardship |
| 5 | CARES | Plural noun, the older literary sense |
| 5 | PAINS | Noun or verb, both work |
| 5 | VEXES | Verb, formal register |
| 6 | UPSETS | Verb, or a noun in sports grids |
| 7 | WORRIES | Noun or verb, the longest common fill |
Cares is the fill that reads as old fashioned
CARES meaning burdens is a register above the rest. It belongs to hymns, ballads and the phrase without a care in the world, and modern prose has narrowed care down to attention and affection. When an editor wants CARES, the clue usually signals the register with a poetic or archaic hint, or leans on a phrase like cast your cares. If the wording is flat and journalistic, five squares are more likely to want PAINS.
The same logic sorts the verbs. IRKS is the mildest, covering irritation rather than hardship, so a clue about serious trouble is unlikely to want it. VEXES sits higher and older. AILS is the one that stays available across every level of formality, which is why it is the safest verb guess at four letters.
When the clue means Northern Ireland
Capitalized, the Troubles is the standard name for the long conflict in Northern Ireland, and a clue that mentions Belfast, Ulster or Irish history is pointing at that sense rather than at any synonym. American grids reach for it rarely, but it does happen, and the giveaway is always a proper noun somewhere in the wording.
More often than not, though, a one word Troubles clue in a daily puzzle is the plain synonym, and four squares ending in S is what you are filling. If ILLS fights a crossing, try WOES before you rethink the whole entry, because the two differ in every position and a single confirmed letter separates them.
Frequently asked questions
Is the answer to Troubles a noun or a verb?
It can be either, since the clue word is spelled the same both ways. Noun readings give ILLS, WOES or CARES, and verb readings give AILS, IRKS or VEXES.
What is the four letter answer to Troubles?
ILLS is the most common, with WOES and AILS also fitting four squares. Since none of the three share a letter position, one crossing is enough to tell them apart.
When is the answer WORRIES?
WORRIES is the standard seven letter fill and works for both the noun and the verb reading, so it needs no special clue signal beyond the square count.
