Definition, Usage, and Examples"},"content":{"rendered":"

Indubitably<\/em> is one of those adverbs that earns its place in a sentence by doing something more specific than simpler alternatives. It does not just mean “certainly” or “probably” \u2014 it carries a precise logical claim: that the matter in question is not capable of being doubted, not merely that the speaker is confident about it.<\/p>\n

Definition<\/h1>\n

Indubitably<\/strong> (adverb): in a way that cannot be doubted; unquestionably; beyond all doubt.<\/p>\n

From Merriam-Webster: “in an indubitable manner; unquestionably.”<\/em><\/p>\n

The key word in that definition is “cannot be doubted” \u2014 not is not doubted but<\/em>\u00a0cannot be<\/em>. The word makes a claim about the nature of the fact, not just the speaker’s confidence level. This is what distinguishes it from the several near synonyms that cluster around it.<\/p>\n

Etymology<\/h1>\n

Indubitably<\/em> derives from the Latin indubitabilis<\/em> \u2014 from in-<\/em> (not) + dubitabilis<\/em> (capable of being doubted), which comes in turn from dubitare<\/em> (to doubt). The -bilis<\/em> suffix in Latin forms adjectives denoting capacity or possibility, so indubitabilis<\/em> means “not able to be doubted” rather than simply “not doubted.” This etymological precision carries through into the English word’s usage today.<\/p>\n

It entered English in the early 17th century, already with its formal, emphatic register intact.<\/p>\n

How it differs from near synonyms<\/h1>\n

Certainly,<\/strong> is the most common near-synonym and the most flexible in register. It expresses high confidence but doesn’t make the stronger claim that doubt is impossible: She will certainly attend.<\/em><\/p>\n

Undoubtedly<\/strong> is close to indubitably<\/em> in meaning \u2014 “without doubt” \u2014 but is somewhat less formal and slightly more common in everyday writing: This is undoubtedly their best work.<\/em><\/p>\n

Unquestionably<\/strong> emphasizes that the matter should not be questioned or challenged, often with a tone of authority: He is unquestionably the most qualified candidate.<\/em><\/p>\n

Doubtless<\/strong> is more hedged in practice than it sounds \u2014 in contemporary usage, Garner notes that doubtless<\/em> often functions as a near-equivalent of probably<\/em> rather than as an absolute claim. Indubitably<\/em> does not carry that hedging quality.<\/p>\n

Indubitably<\/strong> sits at the most formal, most emphatic end of this group. It is appropriate when the claim being made is presented as beyond rational dispute, not merely as highly probable.<\/p>\n

How to use it in a sentence<\/h1>\n

Indubitably<\/em> modifies verbs, adjectives, and entire clauses. It works best at the beginning or end of a sentence for emphasis, or just before the element it modifies:<\/p>\n
