WELLS, Judge.
These proceedings were initiated and determined pursuant to the pertinent provisions of Chapter 35A, Incompetency and Guardianship, N.C.Gen.Stat. Chapter 35A (1987). The Clerk of Superior Court has the responsibility and authority to appoint guardians for incompetent persons. Article 5, Chapter 35A. Article 13 of the Act provides for termination of guardianship, and § 35A-1290 provides in pertinent part:
(a) The clerk has the power and authority on information or complaint made to remove any guardian appointed under the provisions of this Subchapter, to appoint successor guardians, and to make rules or enter orders for the better management of estates and the better care and maintenance of wards and their dependents.
(b) It is the clerk's duty to remove a guardian or to take other action sufficient to protect the ward's interest in the following cases:
* * * * * *
(7) The guardian has a private interest, whether direct or indirect, that might tend to hinder or be adverse to carrying out his duties as guardian.
In this case, the Assistant Clerk applied the provisions of § 35A-1290(b)(7) in finding and concluding that respondents had private interests, both direct and indirect, that might tend to hinder or be adverse to carrying out their duties as guardians. The questions presented to the Superior Court on appeal from the Assistant Clerk and to this Court on appeal from the Superior Court are: (1) whether the Assistant Clerk's findings of fact are supported by the evidence, and (2) whether those findings support the Assistant Clerk's conclusions and order. In re Estate of Lowther, 271 N.C. 345, 156 S.E.2d 693 (1967); In re Estate of Moore, 25 N.C.App. 36, 212 S.E.2d 184, cert. denied, 287 N.C. 259, 214 S.E.2d 430 (1975).
The Assistant Clerk's dispositive findings of fact, not challenged by respondents and therefore deemed to be supported by the evidence, are as follows:

Edward M. Armfield, Jr. and Everette Sherrill have private interests, both direct *220 and indirect, that might tend to hinder or be adverse to carrying out their duties as guardians.

Upon the foregoing findings, the assistant clerk made the following conclusion:

CONCLUSIONS OF LAW

1.
Edward M. Armfield, Jr. and Everette Sherrill have private interests, both direct and indirect, that might tend to hinder or be adverse to carrying out their duties as guardians.
* * * * * *
It was upon these findings and this conclusion that the Assistant Clerk applied the statute to order respondents' removal. We are not aware of any previous decision of our appellate courts interpreting § 35A-1290(b)(7), but we find guidance and direction in previous decisions of our courts in the area of the administration of estates and trusts.
Chapter 28A of our General Statutes, dealing with the administration of decedent's estates, contains a removal provision identical in legal context to § 35A-1290(b)(7). Respondents argue that the Superior Court erred in affirming the order of the Assistant Clerk granting the petition to remove respondents as guardians of Britt Millis Armfield, II because removal under § 35A-1290(b)(7) requires a showing that the private interest of the guardian has an actual and adverse effect upon the interests of the ward.
In In re Moore, 292 N.C. 58, 231 S.E.2d 849 (1977), our Supreme Court concluded that "it is not necessary to show an actual conflict of interest to justify a refusal to issue letters of administration; it is sufficient that the likelihood of a conflict is shown." Cause for revocation of letters under § 28A-9-1 exists "when conditions arise after [a personal representative's] appointment which will prevent him from faithfully and impartially executing the duties which he has assumed." Id. Consistently, this Court has held that, "a person occupying a place of trust and confidence may not place himself in a position where his own interest may conflict with the interest of those for whom he acts." Moore v. Bryson, 11 N.C.App. 260, 181 S.E.2d 113 (1971).
A guardianship is a trust relation and in that relationship the guardian is a trustee who is governed by the same rules that govern other trustees. Owen v. Hines, 227 N.C. 236, 41 S.E.2d 739 (1947). A guardian, like a personal representative, acts in a fiduciary capacity. N.C.Gen.Stat. §§ 32-2 (1991) and 36A-1(a) (1991); Moore, supra. A fiduciary is charged with the duty of acting for the benefit of another party as to matters coming within the scope of the relationship. N.C.Gen.Stat. § 36A-1(a). The duties of a fiduciary include the duty of loyalty and the tradition surrounding this duty is "unbending and inveterate." Trust Co. v. Johnston, 269 N.C. 701, 153 S.E.2d 449 (1967) (quoting Meinhard v. Salmon, 249 N.Y. 458, 164 N.E. 545 (1928)). In interpreting § 35A-1290(b)(7), we must honor this tradition.
When the language of a statute is clear and unambiguous, the courts must give the statute its plain and definite meaning and are without power to interpolate or superimpose provisions and limitations not contained therein. State v. Camp, 286 N.C. 148, 209 S.E.2d 754 (1974). The words "might tend" in § 35A-1290(b)(7) establish a minimal showing of possible conflicting interest for the removal of a guardian. The word "tend" is defined as "to be likely or to be disposed or inclined," and the word "might" is defined as "used to indicate a possibility or probability that is weaker than may." The American Heritage Dictionary (Second College Edition 1982). We hold, therefore, that § 35A-1290(b)(7) authorizes the removal of a guardian where there is a showing of any potential for conflict between the interests of the ward and those of the guardian.
The record in this case discloses substantial potential for conflict between the interests of the ward and respondents. Because respondents are governed by the same rules that govern other trustees they are "held to something stricter than the morals of the marketplace. Not honesty alone, but *221 the punctilio of an honor the most sensitive, is then the standard of behavior.... Only thus has the level of conduct for fiduciaries been kept at a higher level than that trodden by the crowd." Trust Co., supra (quoting Meinhard, supra). The standard established by § 35A-1290(b)(7) acknowledges and confirms the "unbending and inveterate" tradition of fiduciary duty.
Applying the facts in this case to the foregoing principles of law, we hold that the trial court did not err in affirming the order of the Assistant Clerk removing respondents as guardians. The evidence supports the findings of fact and the findings support the conclusion of law that respondents have private interests, both direct and indirect, which might tend to hinder or be adverse to carrying out their duties as guardians.
Based upon our holding, respondents' other assignments of error are without merit and the order of the trial court is
Affirmed.
ARNOLD, C.J., and EAGLES, J., concur.
