Focus – marking the central issue or key fact being discussed.

To draw attention to the core problem or essential detail within a conversation.

When clarification is needed after stating something surprising, ambiguous, or needing further elaboration; e.g., when presenting a cause for concern, correcting a misconception, or highlighting a crucial condition.

Casual spoken interaction (informal chats), written informal correspondence, and everyday dialogue where emphasis on a specific point is desired. Not typical in highly formal academic writing unless used rhetorically.

The thing is

The thing is

clause

• that
• well
• you see

• the point is (more formal)
• what I mean is
• here’s the thing (colloquial variation)

Overusing in overly formal contexts where a more neutral phrasing would be preferable; failing to follow with an actual clause after ‘is’.

what I’m trying to say / that being said / as it turns out

Because it functions idiomatically rather than through literal translation, learners from languages without such discourse markers may struggle and default to word-for-word translations like ‘the issue is’, which sounds unnatural in English conversation.

• Focus-attracting formulas

Creates a brief pause before elaborating on the reason or consequence, signaling to listeners that they should pay special attention to what follows.

Signals transition into explanation mode; signals importance of the upcoming information by drawing focus away from preceding statements.

key point

The chunk 'The thing is' is a versatile discourse marker used to introduce a crucial point, explanation, or justification in conversations. It helps to clarify a situation, correct a misunderstanding, or emphasize an important factor. This expression is particularly useful in informal settings and everyday dialogues where the speaker wants to draw attention to a specific aspect of the discussion. It is less common in formal academic writing unless used rhetorically. Learners should be aware of its idiomatic nature and avoid literal translations from their native language, as this can result in unnatural phrasing. The chunk can be varied slightly to add emphasis or irony, such as 'The funny thing is' or 'The whole thing is'. Common mistakes include overusing it in overly formal contexts or failing to follow it with an actual clause. Similar expressions include 'what I’m trying to say', 'that being said', and 'as it turns out'.
